That's what _path_files always does, only _files will re-try with
directories and all files.

_gdb is rather old and because we've added all that tag-order and
file-patterns stuff in the meantime, I would almost suggest to just use
the `_files -g "*core"' you suggested.  Users can then always use the
two styles to change that if they want (we could add a comment to _gdb
about that, asking users to tell us why they need it -- if the way their
systems handle core dumps is the reason for it).  Of course, they can
now use the file-patterns style to change it to use that pattern, too.

As I said, I had thought about these things when I wrote _gdb, I just
wasn't sure if `*core' is a good enough pattern for all systems.  And I
probably didn't ask back then.

So, I would be happy if you choose to change the call to _files, and
since noone complained that that would break core file completion on
their system...
