Yes, since there are only the two new added callers, if they both want
to switch to wildmatch, then it is fine for the helper function to
switch. The danger is if some other caller wants to start using it; I
added it with the name I did figuring that other spots might want to use
it eventually. But if all of fnmatch is going to go away in favor of
wildmatch eventually, then that helper is not all that useful (or it
would be even more useful as "wildmatch_mem" or similar).

The series only adds two callers, and they provide constant flags;
match_basename passes no flags, and should be OK. match_pathname uses
FNM_PATHNAME, and would need to be converted to use WM_PATHNAME as part
of the conflict resolution.
