There have been nontrivial changes and fixes and I think we're
in a pretty good spot, so I'm planning to release grep-3.5 within
the next two weeks.

Please build and test this and let us know how it goes.

Thanks to Paul Eggert for making so many of the changes here
and to Norihiro Tanaka for helping so much with gnulib's dfa.c.

** Changes in behavior

  The --files-without-match (-L) option has reverted to its behavior
  in grep 3.1 and earlier.  That is, grep -L again succeeds when a
  line is selected, not when a file is listed.  The behavior in grep
  3.2 through 3.4 was causing compatibility problems.

** Bug fixes

  In UTF-8 locales, grep -w no longer ignores a multibyte word
  constituent just before what would otherwise be a word match.
  [Bug#43225 introduced in grep 2.28]

  A performance regression with -E and many patterns has been mostly fixed.
  "Mostly" as there is a performance tradeoff between Bug#22357 and Bug#40634.
  [Bug#40634 introduced in grep 2.28]

  A performance regression with many duplicate patterns has been fixed.
  [Bug#43040 introduced in grep 3.4]

** Build-related

  "make dist" builds .tar.gz files again, as they are still used in
  some barebones builds.
