[PATCH/RFC v2 0/2] add regex match flags to git describe

git describe currently only supports glob matching with the --matches flag. It would be useful to support regular expressions.

For consistency, this uses the same regex flags as those used by git-grep.

Some old discussion of this as a candidate feature is here, though nobody put together a patch as far as I can see: http://comments.gmane.org/gmane.comp.version-control.git/173873

  describe: add option to use perl-compatible regexes with --match
  describe: add basic and extended posix regex matching for completeness
