-     Bruce  Englar  encouraged  the early development of
-the historic eexx/vvii editor.  Peter Kessler  helped  bring
-sanity  to  version  2's command layout.  Bill Joy wrote
-versions 1 and 2.0 through 2.7, and created  the  frame-
-work  that users see in the present editor.  Mark Horton
-added macros and other features and made eexx/vvii work on a
-large number of terminals and Unix systems.

-     NNvvii is originally derived from software contributed
-to the University of California, Berkeley by Steve Kirk-
-endall, the author of the vvii clone eellvviiss.

-     VVii is a screen oriented text editor.   EExx  is  a  line-
-oriented text editor.  EExx and vvii are different interfaces to
-the same program, and it is  possible  to  switch  back  and
-forth  during  an  edit  session.  VViieeww is the equivalent of
-using the --RR (read-only) option of vvii.
-
-     This reference manual is  the  one  provided  with  the
-nneexx/nnvvii  versions  of  the  eexx/vvii text editors.  NNeexx/nnvvii are
-intended as  bug-for-bug  compatible  replacements  for  the
-original  Fourth Berkeley Software Distribution (4BSD) eexx/vvii
-programs.  This reference manual is accompanied by a  tradi-
-tional-style  manual  page.   That manual page describes the
-functionality found in eexx/vvii in far  less  detail  than  the
-description  here.   In  addition,  it  describes the system
-interface to  eexx/vvii,  e.g.  command  line  options,  session
-recovery,  signals,  environmental  variables,  and  similar
-things.
-
-     This reference is intended for users  already  familiar
-with eexx/vvii.  Anyone else should almost certainly read a good
-tutorial on the editor first.  If you are in  an  unfamiliar
-environment,  and you absolutely have to get work done imme-
-diately, see the section entitled "FFaasstt SSttaarrttuupp" in the man-
-ual page.  It is probably enough to get you started.
-
-     There  are a few features in nneexx/nnvvii that are not found
-in historic versions of eexx/vvii.  Some of the more interesting
-of those features are briefly described in the section enti-
-tled "AAddddiittiioonnaall FFeeaattuurreess" near the end  of  this  document.
-For  the rest of this document, nneexx/nnvvii is used only when it
-is necessary to distinguish it from the historic implementa-
-tions of eexx/vvii.
-
-     Future  versions  of this software will be periodically
-made available by anonymous ftp, and can be  retrieved  from
-ffttpp..ccss..bbeerrkkeelleeyy..eedduu, in the directory uuccbb//44bbssdd.

-
-     EExx/vvii  interprets  one  of  two  possible environmental
-variables and reads up to three of five possible files  dur-
-ing  startup.   The variables and files are expected to con-
-tain eexx commands, not vvii commands.  In  addition,  they  are
-interpreted _b_e_f_o_r_e the file to be edited is read, and there-
-fore many eexx commands may not be used.  Generally, any  com-
-mand that requires output to the screen or that needs a file
-upon which to operate, will cause an error if included in  a
-startup file or environmental variable.
-
-     Because  the  eexx  command set supported by nneexx/nnvvii is a
-superset of the command set  supported  by  most  historical

-
-implementations  of  eexx,  nneexx/nnvvii  can use the startup files
-created for the historical implementations, but the converse
-may not be true.
-
-     If  the  --ss (the historic - option) is specified, or if
-standard input is redirected from a file, all  environmental
-variables and startup files are ignored.
-
-     Otherwise,  startup  files  and environmental variables
-are handled in the following order:
-
- (1)   The file //eettcc//vvii..eexxrrcc is read, as long as it is owned
-       by root or the effective user ID of the user.
-
- (2)   The  environmental  variable NNEEXXIINNIITT (or the variable
-       EEXXIINNIITT, if NNEEXXIINNIITT is not set) is interpreted.
-
- (3)   If neither NNEEXXIINNIITT or EEXXIINNIITT was set,  and  the  HHOOMMEE
-       environmental  variable is set, the file $$HHOOMMEE//..nneexxrrcc
-       (or the file $$HHOOMMEE//..eexxrrcc, if  $$HHOOMMEE//..nneexxrrcc  does  not
-       exist)  is  read, as long as the effective user ID of
-       the user is root or is the same as the owner  of  the
-       file.
-
- (4)   If the eexxrrcc option was turned on by one of the previ-
-       ous startup information sources, the file ..nneexxrrcc  (or
-       the file ..eexxrrcc, if ..nneexxrrcc does not exist) is read, as
-       long as the effective user ID of the user is the same
-       as the owner of the file.
-
-     No  startup  file  is  read if it is writable by anyone
-other than its owner.
-
-     It is not an error for any of the startup environmental
-variables or files not to exist.
-
-     Once  all  environmental variables are interpreted, and
-all startup files are read, the first file to be  edited  is
-read  in  (or  a temporary file is created).  Then, any com-
-mands specified using the --cc option  are  executed,  in  the
-context of that file.

-
-     There  is  no  recovery  program  for nneexx/nnvvii, nor does
-nneexx/nnvvii run setuid.  Recovery files are created readable and
-writable  by  the  owner  only.   Users may recover any file
-which they can read, and the superuser may recover any  edit
-session.
-
-     Edit  sessions  are  backed  by  files in the directory
-named    by    the    rreeccddiirr    option    (the     directory
-//vvaarr//ttmmpp//vvii..rreeccoovveerr  by default), and are named "vvii..XXXXXXXXXXXX",

-
-
-where "XXXXXXXXXXXX" is a number related to the process ID.   When
-a  file is first modified, a second recovery file containing
-an email message for the  user  is  created,  and  is  named
-"rreeccoovveerr..XXXXXXXXXXXX",  where, again, "XXXXXXXXXXXX" is associated with
-the process ID.  Both files are removed at the end of a nor-
-mal  edit  session,  but  will remain if the edit session is
-abnormally terminated or the user runs the eexx pprreesseerrvvee  com-
-mand.
-
-     The  rreeccddiirr  option  may be set in either the user's or
-system's startup information, changing the  recovery  direc-
-tory.  (Note, however, that if a memory based file system is
-used as the backup directory, each system reboot will delete
-all  of  the  recovery  files!   The same caution applies to
-directories such as //ttmmpp which are cleared of their contents
-by  a  system  reboot,  or  //uussrr//ttmmpp  which  is periodically
-cleared of old files on many systems.)
-
-     The recovery directory should be owned by root,  or  at
-least  by a pseudo-user.  In addition, if directory "sticky-
-bit" semantics are available, the directory should have  the
-sticky-bit  set  so  that files may only be removed by their
-owners.  The recovery directory must  be  read,  write,  and
-executable by any user, i.e. mode 1777.
-
-     If  the  recovery  directory does not exist, eexx/vvii will
-attempt to create it.   This  can  result  in  the  recovery
-directory  being  owned  by  a normal user, which means that
-that user will be able to remove other user's  recovery  and
-backup files.  This is annoying, but is not a security issue
-as the user cannot otherwise access or modify the files.
-
-     The recovery file has all of the necessary  information
-in  it  to  enable the user to recover the edit session.  In
-addition, it has all of  the  necessary  email  headers  for
-_s_e_n_d_m_a_i_l(8).   When the system is rebooted, all of the files
-in //vvaarr//ttmmpp//vvii..rreeccoovveerr named "rreeccoovveerr..XXXXXXXXXXXX" should be sent
-to  their  owners, by email, using the --tt option of sseennddmmaaiill
-(or  a  similar  mechanism  in  other  mailers).   If  eexx/vvii
-receives  a hangup (SIGHUP) signal, or the user executes the
-eexx pprreesseerrvvee command,  eexx/vvii  will  automatically  email  the
-recovery information to the user.
-
-     If your system does not have the sseennddmmaaiill utility (or a
-mailer program which supports its interface) the source file
-nnvvii//ccoommmmoonn//rreeccoovveerr..cc  will  have  to be modified to use your
-local mail delivery programs.  Note, if nneexx/nnvvii  is  changed
-to  use another mailer, it is important to remember that the
-owner of the file given to the mailer is the  nneexx/nnvvii  user,
-so nothing in the file should be trusted as it may have been
-modified in an effort to compromise the system.

-
-     Finally, the owner execute bit is set on  backup  files
-when  they  are created, and unset when they are first modi-
-fied, e.g. backup files that have no associated email recov-
-ery  file  will  have  this bit set.  (There is also a small
-window where empty files can be created  and  not  yet  have
-this  bit set.  This is due to the method in which the files
-are created.)  Such files should be deleted when the  system
-reboots.
-
-     A  simple  way to do this cleanup is to insert the fol-
-lowing Bourne shell script into your //eettcc//rrcc..llooccaall (or other
-startup)  file.   The  script  should work with the historic
-Bourne shell, a POSIX 1003.2 shell or the  Korn  shell.   (A
-copy      of      this     script     is     included     as
-nnvvii//iinnssttaallll//rreeccoovveerr..ssccrriipptt in the nneexx/nnvvii distribution.)

-     The size of the screen can be set in a number of  ways.
-EExx/vvii  takes  the  following steps until values are obtained
-for both the number of rows and number  of  columns  in  the
-screen.
-
- (1)   If  the  environmental  variable  LLIINNEESS exists, it is
-       used to specify the number of rows in the screen.
-
- (2)   If the environmental variable CCOOLLUUMMNNSS exists,  it  is
-       used  to specify the number of columns in the screen.
-
- (3)   The TIOCGWINSZ _i_o_c_t_l(2) is attempted on the  standard
-       error file descriptor.
-
- (4)   The  termcap  entry  (or  terminfo  entry on System V
-       machines) is checked for the "li"  entry  (rows)  and
-       the "co" entry (columns).
-
- (5)   The  number  of  rows is set to 24, and the number of
-       columns is set to 80.
-
-     If a window change size signal (SIGWINCH) is  received,
-the  new  window  size  is  retrieved  using  the TIOCGWINSZ

-     NNvvii supports multiple screens by  dividing  the  window
-into regions.  It also supports stacks of screens by permit-
-ting the user to change the set of  screens  that  are  cur-
-rently displayed.
-
-     The  command  sspplliitt divides the current screen into two
-regions of approximately equal size.  If a list of files are
-specified  as  arguments  to  the sspplliitt command, the list of
-files to be edited is initialized as if the nneexxtt command had
-been  used.   If no files are specified, the new screen will
-begin by editing the same file as the previous screen.
-
-     When more than one screen is editing a file, changes in
-any  screen  are  reflected in all other screens editing the
-same file.  Exiting any screen without  saving  any  changes
-(or  explicitly discarding them) is permitted until the last
-screen editing the file is exited.
-
-     The  rreessiizzee  command  permits  resizing  of  individual
-screens.  Screens may be grown, shrunk or set to an absolute
-number of rows.
-
-     The ^^WW command is used to switch between screens.  Each
-^^WW  moves  to the next lower screen in the window, or to the
-first screen in the window if there are no lower screens.
-
-     The bbgg command "backgrounds" the current  screen.   The
-screen  disappears from the window, and the rows it occupied
-are taken over by a neighboring screen.  It is an  error  to
-attempt to background the only screen in the window.
-
-     The  ddiissppllaayy  ssccrreeeennss command displays the names of the
-files associated with the current  backgrounded  screens  in
-the window.
-
-     The ffgg [[ffiillee]] command "foregrounds" the first screen in
-the list of backgrounded screens that is associated with its
-argument.   If  no  file  argument  is  specified, the first

-     When the mmaaggiicc option is _n_o_t set, the  only  characters
-with  special  meanings are a "^^" character at the beginning
-of an RE, a "$$" character at the  end  of  an  RE,  and  the
-escaping  character  "\\".   The characters "..", "**", "[[" and
-"~~" are treated as ordinary characters unless preceded by  a

-
-     The  character  "&&" (or "\\&&" if the mmaaggiicc option is _n_o_t
-set) in the replacement string stands for the  text  matched
-by  the  RE  that  is being replaced.  The character "~~" (or
-"\\~~" if the mmaaggiicc option is _n_o_t set) stands for the replace-
-ment  part  of  the previous ssuubbssttiittuuttee command.  It is only
-valid after a ssuubbssttiittuuttee command has been performed.

-     The string "\\##", where "##" is an integer value  from  1
-to  9,  stands for the text matched by the portion of the RE
-enclosed in the "##"'th  set  of  escaped  parentheses,  e.g.
-"\\(("  and  "\\))".   For example, "ss//aabbcc\\((..**\\))ddeeff//\\11//" deletes
-the strings "aabbcc" and "ddeeff" from the matched pattern.
-
-     The strings "\\ll", "\\uu", "\\LL" and "\\UU" can  be  used  to
-modify  the case of elements in the replacement string.  The
-string "\\ll" causes the next character  to  be  converted  to
-lowercase;  the  string "\\uu" behaves similarly, but converts
-to uppercase (e.g.  ss//aabbcc//\\UU&&// replaces the string aabbcc  with
-AABBCC).   The  strings "\\LL" causes characters up to the end of
-the string or the next occurrence of  the  strings  "\\ee"  or
-"\\EE"  to  be converted to lowercase; the string "\\UU" behaves
-similarly, but converts to uppercase.
-
-     If the entire replacement pattern is "%%", then the last
-replacement pattern is used again.
-
-     In  vvii,  inserting  a  <<ccoonnttrrooll--MM>> into the replacement
-string will cause the matched line  to  be  split  into  two
-lines at that point.  (The <<ccoonnttrrooll--MM>> will be discarded.)

-
-     When  eexx or vvii are executed, the text of a file is read
-(or a temporary file  is  created),  and  then  all  editing
-changes  happen  within the context of the copy of the file.

-
-     All files are locked (using the  _f_l_o_c_k(2)  or  _f_c_n_t_l(2)
-interfaces)  during the edit session, to avoid inadvertently
-making modifications to multiple copies of the file.   If  a
-lock  cannot  be obtained for a file because it is locked by
-another process, the edit session is read-only  (as  if  the
-rreeaaddoonnllyy  option  or  the --RR flag had been specified).  If a
-lock cannot be obtained for other reasons, the edit  session
-will  continue,  but  the  file  status information (see the
-<<ccoonnttrrooll--GG>> command) will reflect this fact.
-
-     Both eexx and vvii are modeful editors, i.e. they have  two
-modes,  "command" mode and "text input" mode.  The former is
-intended to permit you  to  enter  commands  which  modifies
-already existing text.  The latter is intended to permit you
-to enter new text.  When eexx first starts running, it  is  in
-command  mode, and usually displays a prompt (see the pprroommpptt
-option for more information).  The prompt is a single  colon
-("::")  character.   There  are three commands that switch eexx
-into text input mode: aappppeenndd, cchhaannggee and  iinnsseerrtt.   Once  in
-input  mode, entering a line containing only a single period

-mode, where the prompt is redisplayed.
-
-     When  vvii first starts running, it is in command mode as
-well.  There are eleven commands that switch  vvii  into  text
-input  mode:  AA,  aa,  CC, cc, II, ii, OO, oo, RR, SS and ss.  Once in
-input mode, entering an <<eessccaappee>> character  terminates  text
-input mode and returns to command mode.
-
-     The  following  words have special meanings in both the
-eexx and vvii command descriptions:
-
-<<iinntteerrrruupptt>>
-     The interrupt character is used to interrupt  the  cur-
-     rent operation.  Normally <<ccoonnttrrooll--CC>>, whatever charac-
-     ter is set for the current terminal is used.
-
-<<lliitteerraall nneexxtt>>
-     The literal next character is used to escape the subse-
-     quent character from any special meaning.  This charac-
-     ter is always <<ccoonnttrrooll--VV>>.  If the terminal is not  set
-     up  to  do  XON/XOFF  flow control, then <<ccoonnttrrooll--QQ>> is
-     used to mean literal next as well.
-
-ccuurrrreenntt ppaatthhnnaammee
-     The pathname of the file currently being edited by  vi.
-     When the percent character ("%%") appears in a file name
-     entered as part  of  an  eexx  command  argument,  it  is
-     replaced  by  the current pathname.  (The "%%" character
-     can be escaped by preceding it with a backslash.)
-
-aalltteerrnnaattee ppaatthhnnaammee
-     The name of the last file name mentioned in an eexx  com-
-     mand,  or,  the  previous  current pathname if the last
-     file mentioned becomes the current file.  When the hash
-     mark  character ("##") appears in a file name entered as
-     part of an eexx command argument, it is replaced  by  the
-     alternate  pathname.  (The "##" character can be escaped
-     by preceding it with a backslash.)
-
-bbuuffffeerr
-     One of a number of named areas  for  saving  copies  of
-     text.  Commands that change or delete text can save the
-     changed or deleted text into  a  specific  buffer,  for
-     later use, if the command allows it (i.e. the eexx cchhaannggee
-     command  cannot  save  the  changed  text  in  a  named
-     buffer).   Buffers  are  named with a single character,
-     preceded by a double quote, e.g.   ""<<cchhaarraacctteerr>>.   His-
-     toric  implementations  of eexx/vvii limited <<cchhaarraacctteerr>> to
-     the alphanumeric characters; nneexx/nnvvii permits the use of
-     any character.

-
-     named  by  the English character "AA" is the same as the
-     buffer named by the character "aa", with  the  exception
-     that, if the buffer contents are being changed (as with
-     a text deletion or vvii  cchhaannggee  command),  the  text  is
-     _a_p_p_e_n_d_e_d  to  the buffer, instead of replacing the cur-
-     rent contents.
-
-     The  buffers  named  by  the  numeric  characters   (in
-     English,  "11"  through "99"), are special, in that if at
-     least one line is changed or deleted in the file, (or a
-     command changes or deletes a region that crosses a line
-     boundary) a copy of the text is placed into the numeric
-     buffer  "11",  regardless of the user specifying another
-     buffer in which to save it.  Before this copy is  done,
-     the  previous  contents  of  buffer  "11" are moved into
-     buffer "22", "22" into buffer "33", and so on.   The  con-
-     tents  of buffer "99" are discarded.  In vvii, text may be
-     explicitly stored into the numeric  buffers.   In  this
-     case, the buffer rotation described above occurs before
-     the replacement of the buffer's contents.  (Text cannot
-     be  explicitly  stored  into  the numeric buffers in eexx
-     because of ambiguities that this would cause in the  eexx
-     command syntax.)
-
-     When  a vvii command synopsis shows both a [[bbuuffffeerr]] and a
-     [[ccoouunntt]], they may be presented in any order.
-
-     Finally, all buffers are either "line"  or  "character"
-     oriented.   All  eexx  commands  which  store  text  into
-     buffers are line  oriented.   Some  vvii  commands  which
-     store text into buffers are line oriented, and some are
-     character oriented; the description for each applicable
-     vvii command notes whether text copied into buffers using
-     the command is line or character  oriented.   In  addi-
-     tion,  the vvii command ddiissppllaayy bbuuffffeerrss displays the cur-
-     rent orientation for each buffer.  Generally, the  only
-     importance  attached to this orientation is that if the
-     buffer is subsequently inserted  into  the  text,  line
-     oriented buffers create new lines for each of the lines
-     they contain, and character oriented buffers create new
-     lines for any lines _o_t_h_e_r than the first and last lines
-     they contain.  The first and last  lines  are  inserted
-     into  the text at the current cursor position, becoming
-     part of the current line.  If there is  more  than  one
-     line  in  the  buffer, however, the current line itself
-     will be split.
-
-uunnnnaammeedd bbuuffffeerr
-     The unnamed buffer is a text storage area which is used

-99..  VVii DDeessccrriippttiioonn
-
-     VVii  takes  up  the  entire screen to display the edited
-file, except for the bottom line of the screen.  The  bottom
-line  of the screen is used to enter eexx commands, and for vvii
-error and informational messages.  If no  other  information
-is being displayed, the default display can show the current
-cursor row and cursor column, an indication of  whether  the
-file  has been modified, and the current mode of the editor.
-See the rruulleerr,  sshhoowwddiirrttyy  and  sshhoowwmmooddee  options  for  more
-information.
-
-     Empty  lines  do not have any special representation on
-the screen, but lines on the  screen  that  would  logically
-come  after  the  end  of the file are displayed as a single
-tilde ("~~") character.  To differentiate between empty lines
-and  lines consisting of only whitespace characters, use the
-lliisstt option.  Historically, implementations of vvii have  also
-displayed  some  lines  as single asterisk ("@@") characters.
-These were lines that were  not  correctly  displayed,  i.e.
-lines  on the screen that did not correspond to lines in the
-file, or lines that did not fit on the current screen.   NNvvii
-never displays lines in this fashion.
-
-     VVii  is  a  modeful editor, i.e. it has two modes, "com-
-mand" mode and "text input" mode.  When vvii first starts,  it
-is  in command mode.  There are several commands that change
-vvii into text input mode.  The <<eessccaappee>> character is used  to
-resolve  the  text  input  into the file, and exit back into
-command mode.  In vvii command  mode,  the  cursor  is  always
-positioned  on  the  last column of characters which take up
-more than one column on the screen.  In vvii text insert mode,
-the  cursor  is positioned on the first column of characters
-which take up more than one column on the screen.
-
-     Generally, if the cursor line and cursor column are not
-on  the  screen,  then the screen is scrolled (if the target
-cursor is close) or repainted (if the target cursor  is  far
-away) so that the cursor is on the screen.  If the screen is
-scrolled, it is moved a minimal amount, and the cursor  line
-will  usually appear at the top or bottom of the screen.  In
-the screen is repainted, the cursor line will appear in  the
-center  of  the  screen,  unless  the cursor is sufficiently
-close to the beginning or end of the file that this  is  not
-possible.  If the lleeffttrriigghhtt option is set, the screen may be
-scrolled or repainted in a horizontal direction as  well  as
-in a vertical one.
-
-     A  major difference between the historical vvii presenta-
-tion and nnvvii is in the scrolling and screen  oriented  posi-
-tion  commands, <<ccoonnttrrooll--BB>>, <<ccoonnttrrooll--DD>>, <<ccoonnttrrooll--EE>>, <<ccoonn--
-ttrrooll--FF>>, <<ccoonnttrrooll--UU>>, <<ccoonnttrrooll--YY>>, HH, LL and MM.  In  histori-
-cal  implementations of vvii, these commands acted on physical

-(as opposed to logical, or screen) lines.   For  lines  that
-were  sufficiently  long  in  relation  to  the  size of the
-screen, this meant that single line  scroll  commands  might
-repaint  the  entire screen, scrolling or screen positioning
-command might not change the screen or move  the  cursor  at
-all,  and  some  lines  simply  could not be displayed, even
-though vvii would edit the file that contained them.  In  nnvvii,
-these  commands  act on logical, i.e. screen lines.  You are
-unlikely to notice any difference  unless  you  are  editing
-files with lines significantly longer than a screen width.
-
-     VVii  keeps track of the currently "most attractive" cur-
-sor position.  Each command description (for  commands  that
-can  change  the  current cursor position), specifies if the
-cursor is set to a specific location in the line, or  if  it
-is moved to the "most attractive cursor position".  The lat-
-ter means that the cursor is moved to  the  cursor  position
-that  is vertically as close as possible to the current cur-
-sor position.  If the current line is shorter than the  cur-
-sor  position  vvii  would select, the cursor is positioned on
-the last character in the line.  (If the line is empty,  the
-cursor is positioned on the first column of the line.)  If a
-command moves the cursor to the most attractive position, it
-does not alter the current cursor position, and a subsequent
-movement will again attempt to move the cursor to that posi-
-tion.  Therefore, although a movement to a line shorter than
-the currently most attractive position will cause the cursor
-to  move to the end of that line, a subsequent movement to a
-longer line will cause the cursor to move back to  the  most
-attractive position.
-
-     In  addition,  the $$ command makes the end of each line
-the most attractive cursor position rather than  a  specific
-column.
-
-     Each  vvii command described below notes where the cursor
-ends up after it is executed.  This position is described in
-terms of characters on the line, i.e.  "the previous charac-
-ter", or, "the last character in  the  line".   This  is  to
-avoid  needing  to  continually refer to on what part of the
-character the cursor rests.
-
-     The following words have special meaning  for  vvii  com-
-mands.
-
-pprreevviioouuss ccoonntteexxtt
-     The  position  of  the  cursor before the command which
-     caused the last absolute movement was  executed.   Each
-     vvii  command  described in the next section that is con-
-     sidered an absolute movement is so noted.  In addition,
-     specifying  _a_n_y  address to an eexx command is considered
-     an absolute movement.

-     A second vvii command can be used as an optional trailing
-     argument  to the vvii !!, <<, >>, cc, dd, yy, and (depending on
-     the ttiillddeeoopp option) ~~ commands.  This command indicates
-     the  end  of  the region of text that's affected by the
-     command.  The motion command may be either the  command
-     character  repeated (in which case it means the current
-     line) or a cursor  movement  command.   In  the  latter
-     case,  the  region  affected by the command is from the
-     starting or stopping cursor position which comes  first
-     in  the  file,  to  immediately  before the starting or
-     stopping cursor position which comes later in the file.
-     Commands  that operate on lines instead of using begin-
-     ning and ending cursor positions operate on all of  the
-     lines  that  are wholly or partially in the region.  In
-     addition, some  other  commands  become  line  oriented

-     The  optional count prefix available for some of the vvii

-     part of the motion argument.  For example, the commands

-     plicative and is considered part of  the  motion  argu-

-     The following section describes the commands  available
-in  the command mode of the vvii editor.  In each entry below,
-the tag line is a usage synopsis for the command  character.
-In  addition,  the  final  line  and column the cursor rests
-upon, and any options which affect the command are noted.

-     ter on  or  after  the  current  cursor  position,  and
-     extends up to the next non-word character or the end of
-     the line.  The search is literal, i.e. no characters in
-     the  word  have any special meaning in terms of Regular
-     Expressions.  It is an error if no matching pattern  is

-     1111..  VVii TTeexxtt IInnppuutt CCoommmmaannddss
-
-          The   following  section  describes  the  commands
-     available in the text input mode of the vvii editor.
-
-          Historically, vvii  implementations  only  permitted
-     the  characters  inserted  on  the  current  line to be
-     erased.  In addition, only the <<ccoonnttrrooll--DD>> erase  char-
-     acter  and  the "00<<ccoonnttrrooll--DD>>" and "^^<<ccoonnttrrooll--DD>>" erase
-     strings could erase autoindent characters.  This imple-
-     mentation  permits  erasure to continue past the begin-
-     ning of the current line, and back to where text  input
-     mode  was  entered.  In addition, autoindent characters
-     may be erased using the standard erase characters.  For
-     the  line  and  word  erase  characters,  reaching  the
-     autoindent characters forms a "soft" boundary, denoting
-     the  end  of the current word or line erase.  Repeating
-     the word or line erase key will  erase  the  autoindent
-     characters.
-
-          Historically, vvii always used <<ccoonnttrrooll--HH>> and <<ccoonn--
-     ttrrooll--WW>> as character and word erase characters, respec-
-     tively,  regardless  of  the current terminal settings.
-     This implementation accepts, in addition to  these  two
-     characters,  the  current terminal characters for those
-     operations.
-
-     <<nnuull>>
-          If the first character of the input  is  a  <<nnuull>>,
-          the   previous  input  is  replayed,  as  if  just
-          entered.
-
-     <<ccoonnttrrooll--DD>>
-          If the previous  character  on  the  line  was  an
-          autoindent character, erase it.  Otherwise, if the
-          user is entering the first character in the  line,
-          <<ccoonnttrrooll--DD>>  is  ignored.   Otherwise,  a  literal
-          <<ccoonnttrrooll--DD>> character is entered.

-          characters on the line.  In addition, the  autoin-
-          dent level is reset to 0.
-
-     00<<ccoonnttrrooll--DD>>
-          If  the  previous  character  on  the  line was an
-          autoindent character, erase all of the  autoindent
-          characters on the line.
-
-     <<ccoonnttrrooll--TT>>
-          Insert  sufficient <<ttaabb>> and <<ssppaaccee>> characters to
-          move the cursor forward to  a  column  immediately
-          after the next column which is an even multiple of
-          the sshhiiffttwwiiddtthh option.
-
-          Historically, vvii did not  permit  the  <<ccoonnttrrooll--TT>>
-          command  to  be  used unless the cursor was at the
-          first column of a new line or it was preceded only
-          by  autoindent  characters.   NNvvii permits it to be
-          used at any time during insert mode.
-
-     <<eerraassee>>
-     <<ccoonnttrrooll--HH>>
-          Erase the last character.
-
-     <<lliitteerraall nneexxtt>>
-          Quote the next character.  The next character will
-          not be mapped (see the mmaapp command for more infor-
-          mation) or interpreted specially.  A  carat  ("^^")
-          character  will  be  displayed  immediately  as  a
-          placeholder, but will  be  replaced  by  the  next
-          character.

-
-     <<ccoonnttrrooll--WW>>

-     1122..  EExx AAddddrreessssiinngg
-
-          Addressing in eexx (and when eexx  commands  are  exe-
-     cuted  from  vvii)  relates to the current line.  In gen-
-     eral, the current line is the last line affected  by  a
-     command.   The exact effect on the current line is dis-
-     cussed under the description of each command.  When the
-     file contains no lines, the current line is zero.
-
-          Addresses  are  constructed  by one or more of the
-     following methods:
-
-      (1)   The address ".."  refers to the current line.
-
-      (2)   The address "$$" refers to the last line  of  the
-            file.
-
-      (3)   The  address  "NN", where NN is a positive number,
-            refers to the N-th line of the file.
-
-      (4)   The  address  "''<<cchhaarraacctteerr>>"  or  "``<<cchhaarraacctteerr>>"
-            refers to the line marked with the name <<cchhaarraacc--
-            tteerr>>.  (See the kk or mm commands for more  infor-
-            mation on how to mark lines.)
-
-      (5)   A  regular  expression  (RE) enclosed by slashes
-            ("//") is an address, and it refers to the  first
-            line  found  by  searching forward from the line
-            _a_f_t_e_r the current line toward  the  end  of  the
-            file,  and stopping at the first line containing
-            a string matching the RE.  (The  trailing  slash
-            can  be omitted at the end of the command line.)
-
-            If no RE is specified, i.e. the pattern is "////",
-            the  last  RE used in any command is used in the
-            search.
-
-            If the eexxtteennddeedd option is set, the RE is handled
-            as an extended RE, not a basic RE.  If the wwrraapp--
-            ssccaann option is set, the search wraps  around  to
-            the  beginning  of  the file and continues up to
-            and including the  current  line,  so  that  the
-            entire file is searched.
-
-            The  form "\\//" is accepted for historic reasons,
-            and is identical to "////".
-
-      (6)   An  RE  enclosed   in   question   marks   ("??")
-            addresses  the  first  line  found  by searching
-            backward from the  line  _p_r_e_c_e_d_i_n_g  the  current

-            line, toward the beginning of the file and stop-
-            ping at  the  first  line  containing  a  string
-            matching  the  RE.   (The trailing question mark
-            can be omitted at the end of a command line.)
-
-            If no RE is specified, i.e. the pattern is "????",
-            the  last  RE used in any command is used in the
-            search.
-
-            If the eexxtteennddeedd option is set, the RE is handled
-            as an extended RE, not a basic RE.  If the wwrraapp--
-            ssccaann option is set,  the  search   wraps  around
-            from the beginning of the file to the end of the
-            file and continues up to and including the  cur-
-            rent  line, so that the entire file is searched.
-
-            The form "\\??"  is accepted for historic reasons,
-            and is identical to "????".
-
-      (7)   An  address  followed  by a plus sign ("++") or a
-            minus sign ("--") followed by a number is an off-
-            set  address  and refers to the address plus (or
-            minus) the indicated number of  lines.   If  the
-            address  is omitted, the addition or subtraction
-            is done with respect to the current line.
-
-      (8)   An address of "++" or "--" followed by a number is
-            an  offset  from the current line.  For example,
-            "--55" is the same as "..--55".
-
-      (9)   An address ending with "++" or "--" has 1 added to
-            or  subtracted  from  the address, respectively.
-            As a consequence of this rule and of the  previ-
-            ous  rule,  the  address  "--" refers to the line
-            preceding the current line.  Moreover,  trailing
-            "++" and "--" characters have a cumulative effect.
-            For example, "++++--++++" refers to the current  line
-            plus 3.
-
-      (10)  A  percent  sign  ("%%")  is  equivalent  to  the
-            address range "11,,$$".
-
-          EExx commands require zero, one, or  two  addresses.
-     It is an error to specify an address to a command which
-     requires zero addresses.
-
-          If the user provides more than the expected number
-     of  addresses  to  any  eexx command, the first addresses
-     specified are discarded.  For  example,  "11,,22,,33,,55"print
-     prints  lines  3  through  5, because the pprriinntt command
-     only takes two addresses.

-
-          The addresses in a range are separated  from  each
-     other  by  a  comma (",,") or a semicolon (";;").  In the
-     latter case, the current line  ("..")   is  set  to  the
-     first address, and only then is the second address cal-
-     culated.  This feature can be  used  to  determine  the
-     starting  line  for  forward and backward searches (see
-     rules (5) and (6) above).  The second  address  of  any
-     two-address  sequence  corresponds  to a line that fol-
-     lows, in the file, the line corresponding to the  first
-     address.   The first address must be less than or equal
-     to the second  address.   The  first  address  must  be
-     greater  than  or  equal to the first line of the file,
-     and the last address must be less than or equal to  the
-     last line of the file.

-
-          The  following  words have special meanings for eexx
-     commands.
-
-     <<eeooff>>
-          The end-of-file character is used  to  scroll  the
-          screen  in  the eexx editor.  This character is nor-
-          mally <<ccoonnttrrooll--DD>>, however, whatever character  is
-          set for the current terminal is used.
-
-     lliinnee
-          A  single-line  address, given in any of the forms
-          described in the section entitled "EExx AAddddrreessssiinngg".
-          The default for lliinnee is the current line.
-
-     rraannggee
-          A  line, or a pair of line addresses, separated by
-          a comma or semicolon.  (See the  section  entitled
-          "EExx   AAddddrreessssiinngg"   for  more  information.)   The
-          default for range is the current line  _o_n_l_y,  i.e.
-          "..,,..".   A percent sign ("%%") stands for the range
-          "11,,$$".  The starting address must be less than, or
-          equal to, the ending address.
-
-     ccoouunntt
-          A positive integer, specifying the number of lines
-          to be affected by the command; the default  is  1.
-          Generally,  a  count  past  the end-of-file may be
-          specified, e.g. the command "pp 33000000" in a 10  line
-          file  is  acceptable, and will print from the cur-
-          rent line through the last line in the file.
-
-     ffllaaggss
-          One or more of the characters "#", "p",  and  "l".
-          When a command that accepts these flags completes,
-          the addressed line(s) are written out as if by the
-          corresponding  ##,  ll  or pp commands.  In addition,

-
-
-          any number of "++" or "--" characters can be  speci-
-          fied  before, after, or during the flags, in which
-          case the line written is not necessarily  the  one
-          affected  by  the  command,  but  rather  the line
-          addressed by the offset  address  specified.   The
-          default for ffllaaggss is none.
-
-     ffiillee
-          A  pattern  used to derive a pathname; the default
-          is the current file.  File names are subjected  to
-          normal _s_h(1) word expansions.
-
-          Anywhere a file name is specified, it is also pos-
-     sible to use the special string "//ttmmpp".  This  will  be
-     replaced  with  a temporary file name which can be used
-     for temporary work, e.g.  "::ee //ttmmpp" creates and edits a
-     new file.
-
-          If both a count and a range are specified for com-
-     mands that use either, the starting line for  the  com-
-     mand  is  the  _l_a_s_t  line  addressed  by the range, and
-     ccoouunntt- subsequent lines are affected  by  the  command,
-     e.g.  the  command "22,,33pp44" prints out lines 3, 4, 5 and
-     6.
-
-          When only a line or range is  specified,  with  no
-     command,  the  implied command is either a lliisstt, nnuummbbeerr
-     or pprriinntt command.  The command used is the most  recent
-     of  the three commands to have been used (including any
-     use as a flag).  If none of these  commands  have  been
-     used  before, the pprriinntt command is the implied command.
-     When no range or count is  specified  and  the  command
-     line  is  a blank line, the current line is incremented
-     by 1 and then the current line is displayed.
-
-          Zero or more whitespace characters may precede  or
-     follow  the  addresses,  count, flags, or command name.
-     Any object following a command name  (such  as  buffer,
-     file,  etc.), that begins with an alphabetic character,
-     should be separated from the command name by  at  least
-     one whitespace character.
-
-          Any  character,  including  <<ccaarrrriiaaggee--rreettuurrnn>>, "%%"
-     and "##" retain their literal value when preceded  by  a
-     backslash.

-          The   following  section  describes  the  commands
-     available in the eexx editor.  In each entry  below,  the

-
-          Each  command  can  be entered as the abbreviation
-     (those characters in the synopsis command word  preced-
-     ing  the  "[" character), the full command (all charac-
-     ters shown for the command word, omitting the  "["  and
-     "]" characters), or any leading subset of the full com-
-     mand down to the abbreviation.  For example,  the  args
-     command  (shown  as  "aarr[[ggss]]"  in  the synopsis) can be
-     entered as "aarr", "aarrgg" or "aarrggss".
-
-          Each eexx command described below notes the new cur-
-     rent  line after it is executed, as well as any options
-     that affect the command.
-
-     ""
-          A comment.  Command lines beginning with the  dou-
-          ble-quote  character ("""") are ignored.  This per-
-          mits comments in editor scripts and startup files.
-
-     <<eenndd--ooff--ffiillee>>
-          Scroll  the screen.  Write the next N lines, where
-          N is the value of the ssccrroollll option.  The  command
-          is  the  end-of-file terminal character, which may
-          be different on different  terminals.   Tradition-
-          ally, it is the <<ccoonnttrrooll--DD>> key.
-
-          Historically,  the eeooff command ignored any preced-
-          ing count, and  the  <<eenndd--ooff--ffiillee>>  character  was
-          ignored unless it was entered as the first charac-
-          ter of the command.  This implementation treats it
-          as  a command _o_n_l_y if entered as the first charac-
-          ter of the command line, and otherwise  treats  it
-          as any other character.

-     [[rraannggee]]!! aarrgguummeenntt((ss))
-          Execute a shell command, or filter lines through a
-          shell command.  In the first synopsis, the remain-
-          der of the line after the "!!"  character is passed
-          to the program named by the  sshheellll  option,  as  a
-          single argument.
-
-          Within  the  rest  of  the  line,  "%%" and "##" are
-          expanded into the current and alternate pathnames,
-          respectively.  The character "!!"  is expanded with
-          the command  text  of  the  previous  !!   command.
-          (Therefore, the command !!!!  repeats the previous !!
-          command.)  The special meanings of "%%",  "##",  and
-          "!!"   can  be  overridden  by escaping them with a
-          backslash.  If no !!  or ::!!  command has  yet  been
-          executed,  it  is an error to use an unescaped "!!"

-          expansion  on  the  strings provided as arguments.

-     nneexx/nnvvii.   Historically,  only  the  full  name and the
-     official abbreviations were accepted by  eexx/vvii.   Using
-     full  names  in  your  startup  files and environmental
-     variables will probably make them more portable.)   The
-     part  in  square  brackets  is the default value of the
-     option.  Most of the options are boolean, i.e. they are
-     either  on or off, and do not have an associated value.
-
-          Options apply to both eexx and vvii modes, unless oth-
-     erwise specified.

-     aallttwweerraassee [[ooffff]]
-          VVii  only.   Change  how  vvii does word erase during
-          text input.  When this option is set, text is bro-
-          ken up into three classes: alphabetic, numeric and
-          underscore characters, other nonblank  characters,
-          and  blank characters.  Changing from one class to
-          another marks the end of a word.  In addition, the
-          class  of  the  first  character erased is ignored
-          (which is exactly what you want when erasing path-
-          name components).
-
-     aauuttooiinnddeenntt,, aaii [[ooffff]]
-          If  this  option is set, whenever you create a new
-          line (using the vvii AA, aa, CC, cc, II, ii, OO, oo,  RR,  rr,
-          SS,  and  ss commands, or the eexx aappppeenndd, cchhaannggee, and
-          iinnsseerrtt commands) the  new  line  is  automatically
-          indented  to  align the cursor with the first non-
-          blank character of the line from which you created
-          it.   Lines  are  indented using tab characters to
-          the extent possible (based on  the  value  of  the
-          ttaabbssttoopp option) and then using space characters as
-          necessary.  For commands inserting text  into  the
-          middle  of  a  line,  any  blank characters to the
-          right of the cursor are discarded, and  the  first
-          nonblank  character  to the right of the cursor is
-          aligned as described above.
-
-          The indent characters are themselves somewhat spe-
-          cial.   If you do not enter more characters on the
-          new line before moving to another line, or  enter-
-          ing <<eessccaappee>>, the indent character will be deleted
-          and the line will be empty.  For example,  if  you
-          enter  <<ccaarrrriiaaggee--rreettuurrnn>>  twice in succession, the
-          line created by the first  <<ccaarrrriiaaggee--rreettuurrnn>>  will
-          not  have  any characters in it, regardless of the
-          indentation of the previous or subsequent line.

-
-
-          Indent characters  also  require  that  you  enter
-          additional  erase  characters to delete them.  For
-          example, if you have an indented line,  containing
-          only  blanks, the first <<wwoorrdd--eerraassee>> character you
-          enter will erase up to end of the  indent  charac-
-          ters, and the second will erase back to the begin-
-          ning of the line.  (Historically, only  the  <<ccoonn--
-          ttrrooll--DD>>  key  would  erase  the indent characters.
-          Both the <<ccoonnttrrooll--DD>> key and the usual erase  keys
-          work in nnvvii.)  In addition, if the cursor is posi-
-          tioned at the end of the  indent  characters,  the
-          keys  "00<<ccoonnttrrooll--DD>>"  will erase all of the indent
-          characters for the  current  line,  resetting  the
-          indentation  level  to  0.   Similarly,  the  keys
-          "^^<<ccoonnttrrooll--DD>>" will erase all of the indent  char-
-          acters  for the current line, leaving the indenta-
-          tion level for future created lines unaffected.
-
-          Finally, if the aauuttooiinnddeenntt option is  set,  the  SS
-          and  cccc commands change from the first nonblank of
-          the line to the end of the line, instead  of  from
-          the  beginning of the line to the end of the line.

-          movements will  result  in  displaying  only  that
-          smaller  number  of lines on the screen.  (Further
-          movements in that same area  will  result  in  the
-          screen  being filled.)  This can provide a perfor-
-          mance improvement when viewing different places in
-          one or more files over a slow link.

-          VVii only.  If the value of the wwrraappmmaarrggiinn option is
-          non-zero, vvii will split lines so that they end  at
-          least  that number of characters before the right-
-          hand margin of the screen.  (Note,  the  value  of
-          wwrraappmmaarrggiinn is _n_o_t a text length.  In a screen that
-          is 80 columns wide,  the  command  "::sseett  wwrraappmmaarr--
-          ggiinn==88"  attempts  to  keep  the lines less than or
-          equal to 72 columns wide.)
-
-          Lines are split at the previous whitespace charac-
-          ter  closest  to the number.  Any trailing whites-
-          pace characters before that character are deleted.
-          If  the  line  is  split  because  of  an inserted
-          <<ssppaaccee>> or <<ttaabb>> character,  and  you  then  enter
-          another <<ssppaaccee>> character, it is discarded.
-
-          If wrapmargin is set to 0, or if there is no blank
-          character upon which to split the line,  the  line
-          is not broken.

-          This option causes searches to wrap around the end

-
-          There  are  a few features in nneexx/nnvvii that are not
-     found in historic versions of eexx/vvii.  Some of the  more
-     interesting of those features are as follows:
-
-     88--bbiitt cclleeaann ddaattaa,, llaarrggee lliinneess,, ffiilleess
-          NNeexx/nnvvii  will  edit any format file.  Line lengths
-          are limited by available memory,  and  file  sizes
-          are  limited by available disk space.  The vvii text
-          input mode command <<ccoonnttrrooll--XX>> can insert any pos-
-          sible character value into the text.
-
-     SSpplliitt ssccrreeeennss
-          The sspplliitt command divides the screen into multiple
-          editing regions.  The <<ccoonnttrrooll--WW>> command  rotates
-          between  the  foreground screens.  The rreessiizzee com-
-          mand can be used to grow or  shrink  a  particular
-          screen.
-
-     BBaacckkggrroouunndd aanndd ffoorreeggrroouunndd ssccrreeeennss
-          The bbgg command backgrounds the current screen, and
-          the ffgg command foregrounds  backgrounded  screens.
-          The  ddiissppllaayy command can be used to list the back-
-          ground screens.
-
-     TTaagg ssttaacckkss
-          Tags are now maintained in a stack.  The <<ccoonnttrrooll--
-          TT>>  command  returns to the previous tag location.
-          The ttaaggppoopp command returns to the most recent  tag
-          location  by default, or, optionally to a specific
-          tag number in the tag stack, or  the  most  recent
-          tag  from  a  specified file.  The ddiissppllaayy command
-          can be used to list the tags  stack.   The  ttaaggttoopp
-          command returns to the top of the tag stack.
-
-     NNeeww ddiissppllaayyss
-          The  ddiissppllaayy  command  can  be used to display the
-          current buffers, the backgrounded screens, and the
-          tags stack.
-
-     IInnffiinniittee uunnddoo
-          Changes  made during an edit session may be rolled
-          backward and forward.  A  ..   command  immediately
-          after  a  uu  command  continues  either forward or
-          backward depending on whether the uu command was an
-          undo or a redo.
-
-     UUssaaggee iinnffoorrmmaattiioonn
-          The  eexxuussaaggee  and  vviiuussaaggee  commands provide usage
-          information for all of the eexx and vvii  commands  by
