new snapshot available: grep-2.9.69-f91c

[Jim Meyering]

[resending with corrected auto-generated "To:" address]

I expect to make a stable release in the next week or so.
While there hasn't been much in the way of big changes in grep proper,
it's been longer than I'd like (nearly 5 months), and there have been
many changes in gnulib, including a few portability fixes that affect grep.
If anyone knows of pending patches or issues to consider, please let us know.

Here's the NEWS, so far:
================================================================
** Bug fixes

  grep no longer mishandles high-bit-set pattern bytes on systems
  where "char" is a signed type. [bug appears to affect only MS-Windows]

  grep now rejects a command like "grep -r pattern . > out",
  in which the output file is also one of the inputs,
  because it can result in an "infinite" disk-filling loop.
  [bug present since "the beginning"]

** Build-related

  "make dist" no longer builds .tar.gz files.
  xz is portable enough and in wide-enough use that distributing
  only .tar.xz files is enough.


Here's the not-so-shortlog:
