new snapshot available: grep-3.3.42-088f

[Jim Meyering]

It's been just over a year since the release of grep-3.3. I'm hoping
to make a release before 2020, so any testing you can do soon is most
welcome.

======================================
Here's what NEWS looks like:

** New features

  The new --no-ignore-case option causes grep to observe case
  distinctions, overriding any previous -i (--ignore-case) option.

** Bug fixes

  '.' no longer matches some invalid byte sequences in UTF-8 locales.
  [bug introduced in grep 2.7]

  grep -Fw can no longer false match in non-UTF-8 multibyte locales
  For example, this command would erroneously print its input line:
    echo ab | LC_CTYPE=ja_JP.eucjp grep -Fw b
  [Bug#38223 introduced in grep 2.28]

  The exit status of 'grep -L' is no longer incorrect when standard
  output is /dev/null.
  [Bug#37716 introduced in grep 3.2]

  A performance bug has been fixed when grep is given many patterns
  each of which lack backreferences.
  [Bug#33249 introduced in grep 2.5]

  A performance bug has been fixed for patterns like '01.2' that
  cause grep to reorder tokens internally.
  [Bug#34951 introduced in grep 3.2]

** Build-related

  The build procedure no longer relies on any already-built src/grep
  that might be absent or broken.  Instead, it uses the system 'grep'
  to bootstrap, and uses src/grep only to test the build.  On Solaris
  /usr/bin/grep is broken, but you can install GNU or XPG4 'grep' from
  the standard Solaris distribution before building GNU Grep yourself.
  [bug introduced in grep 2.8]
