I was looking at the code to see how the two file formats differed and
noticed that match_order() doesn't set the WM_PATHNAME flag when it
calls wildmatch().  That's unintentional (a bug), right?

It has been that way from day one IIRC even before we introduced
wildmatch()---IOW it may be intentional that the current code that
uses wildmatch() does not use WM_PATHNAME.

You are the original author (af5323e027 2005-05-30).  Do you remember
what your intention was?

Yes.  

Back then we didn't even have wildmatch(), and used fnmatch()
instead, so forcing FNM_PATHNAME would have meant that people
wouldn't be able to say "foo*bar" to match "foo/other/bar"; with
wildmatch, "foo**bar" lets you defeat WM_PATHNAME so having
WM_PATHNAME always in effect is less of an issue, but with
fnmatch(), having FNM_PATHNAME always in effect has a lot of
downside.

I'd expect that orderfile people have today will be broken and
require tweaking if you switched WM_PATHNAME on.
