Fix handling of unterminated bracket expressions in fnmatch (bug 28792)
When fnmatch processes a bracket expression, and eventually finds it to be
unterminated, it should rescan it, treating the starting bracket as a
normal character. That didn't happen when a matching character was found
while scanning the bracket expression.
