Implementing the "lp" command.

This command is required to exist in terms of compatibility with the
Posix 1003.2 specification.  It actually invokes the lpr service with
the proper options.

+.Sh NAME
+.Nm lp
+.Nd front-end to the print spooler
+.Sh SYNOPSIS
+.Nm lp
+.Op Fl c
+.Op Fl d printer
+.Op Fl n Ar num
+.Op Ar name ...
+.Sh DESCRIPTION
+.Nm Lp
+is a front-end to the print spooler as required by the
+.St -p1003.2
+specification.  It effectively invokes
+.Xr lpr 1
+with the proper set of arguments.
+
+It generally prints the named files on the destination printer.
+.Pp
+Option
+.Fl c
+makes the
+.Nm
+command exit only after further access to any of the input files is no
+longer required.  The application can then safely delete or modify the
+files without affecting the output operation.
+
+To specify a particular printer, option
+.Fl d Ar dest
+can be used.  If no
+.Fl d
+is provided on the command line, the contents of the environmental
+variables
+.Ev LPDEST
+or
+.Ev PRINTER
+.Pq with this precedence
+are taken as the destination printer.
+
+Option
+.Fl n Ar num
+can be used to specify that
+.Ar num
+copies of each of the named files shall be printed.
+
+.Sh ENVIRONMENT
+As described above, the variables
+.Ev LPDEST
+and
+.Ev PRINTER
+are examined to select the destination printer.
+
+.Sh SEE ALSO
+.Xr lpr 1
+.Sh STANDARDS
+The
+.Nm lp
+command is expected to comply with the
+.St -p1003.2
+specification.
+.Sh AUTHOR
+This implementation of the
+.Nm
+command has been written by
+.if t J\(:org Wunsch.
+.if n Joerg Wunsch.
+.Sh BUGS
+The
+.Nm
+command inherits several bugs from the utilities invoked, namely it
+requires any option separated from its argument by a whitespace
+since the getopts implementation of
+.Xr sh 1
+is broken, and it does not honour dashes as input file names
+.Pq meant to use standard input
+since
+.Xr lpr 1
+ignores them.
+
+The
+.St -p1003.2
+specification does not provide any means to print non-text files.  It
+rather requires the files to be printed to be text files limited to
+reasonable line lengths and printable characters.

+# XXX Bugs:
+# . Our lpr command is not smart enough about dashes as input file names,
+#   they should indicate the use of standard input.
+# . Our /bin/sh is not Posix-1003.2 compliant in its getopts command;
+#   if the user specifies an option argument immediately after the
+#   option, the variable OPTIND will be set wrong.  (This way of
+#   specifying option arguments is deprecated by Posix, but explicitly
+#   allowed.)
+# . Our lpr command should allow the Posix-compliant way of specifying
+#   options that take an argument; it currently requires the argument
+#   to follow the option immediately.
