[PATCH/RFC 0/2] add a perl compatible regex match flag to git describe

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

PCRE is already an optional dependency from git grep, I wonder if posix or
extended regexes would be preferable?

Some old discussion of this as a candidate feature is here, though nobody put
together a patch as far as I can see:

  describe: mention glob in the --matches help text
  describe: add --pcre-match option
