Are there (many?) fnmatch patterns that don't match themselves? I'm just
wondering if the extra strcmp is worth-it / needed?

I was a bit confused when reading this (until I saw the calling
context). I guess path is dirname and entry is basename?

Other than needing doc and a test, I don't remember any objections to
this code, although I vaguely remember some alternative proposals for
ignoring?

I guess one point is that we are proposing to use regexps against paths
in one place [1] and proposing to use fnmatch here.  I'm not sure it's
worth trying to be more consistent, but now seems to be the time to
discuss. I think both places could use either, if someone did the
work. Of course the other argument is that the queries should be
consistent among themselves.
