r275687:

  Remove termcap entry reordering; install the file verbatim instead

  termcap entry reordering requires ex (which is available via usr.bin/vi), which
  breaks on build hosts where installworld is run with MK_VI == no (or when
  make delete-old is run on ^/projects/building-blocks as vi, et al, are
  removed on the branch when the knob is tweaked to => "no")

  Reordering termcap was believed to improve performance, but the file is now
  accessed via /etc/termcap.db, so /etc/termcap (and /usr/share/misc/termcap by
  proxy) access is less preferred.

  Reordering the file broke the historical comment <-> entry mapping as well,
  which could muddle the purpose of entries in the file, so it could be
  potentially harmful to readers in its reordered state.

  Discussion took place on hackers@ here:
  https://lists.freebsd.org/pipermail/freebsd-hackers/2014-December/046657.html

  Discussed with: -hackers, mp
  Sponsored by: EMC / Isilon Storage Division

r275692:

  Fix building termcap.db when make obj is run beforehand from a clean tree by
  using make variables for the filenames, which helps resolve pathing
  appropriately when running cap_mkdb

 Third, if you are not a super user and cannot create the directory
 /usr/lib/tabset, make a corresponding directory somewhere you can and add
 a line to reorder to globally change all /usr/lib/tabset's to your own
-path name.  This change is better than just changing the termcap.src file
+path name.  This change is better than just changing the termcap file
 because it makes it easier to diff it from newer distributed versions.
 Try to keep the source as is whenever possible, and put mungings into
 reorder.
