Yes - it supports more than pattern_glob and a bit less than the system

  The g_pattern_match* functions match a string against a pattern
  containing '*' and '?' wildcards with similar semantics as the standard
  glob() function: '*' matches an arbitrary, possibly empty, string, '?'
  matches an arbitrary character.

  Note that in contrast to glob(), the '/' character can be matched by the
  wildcards, there are no '[...]' character ranges and '*' and '?' can not
  be escaped to include them literally in a pattern.

If you give me some example existing pattern forms we can add them to
test-logging. I manually tested both single and double * patterns while
working on the rest of the series.
