bug#22443: new snapshot available: grep-2.22.29-83df

[Jim Meyering]

We would like to make a new bug-fix-only release of grep soon,
so here is a snapshot of the latest sources. Please build and
test on whatever systems you can find, and let us know how
that goes -- reports of success are welcome, too.

** Bug fixes

  Binary files are now less likely to generate diagnostics and more
  likely to yield text matches.  grep now reports "Binary file FOO
  matches" and suppresses further output instead of outputting a line
  containing an encoding error; hence grep can now report matching text
  before a later binary match.  Formerly, grep reported FOO to be
  binary when it found an encoding error in FOO before generating
  output for FOO, which meant it never reported both matching text and
  matching binary data; this was less useful for searching text
  containing encoding errors in non-matching lines.
  [bug introduced in grep-2.21]

  grep -c no longer stops counting when finding binary data.
  [bug introduced in grep-2.21]

  grep no longer outputs encoding errors in unibyte locales.
  For example, if the byte '\x81' is not a valid character in a
  unibyte locale, grep treats the byte as binary data.
  [bug introduced in grep-2.21]

  grep -oP is no longer susceptible to an infinite loop when processing
  invalid UTF8 just before a match.
  [bug introduced in grep-2.22]

  --exclude and related options are now matched against trailing
  parts of command-line arguments, not against the entire arguments.
  This partly reverts the --exclude-related change in 2.22.
  [bug introduced in grep-2.22]

  --line-buffer is no longer ineffective when combined with -l.
  [bug introduced in grep-2.5]

  -xw is now equivalent to -x more consistently, with -P and with backrefs.
  [bug only partially fixed in grep-2.19]
