(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

That first TAB completes to "foo/", though, which is what you'd expect.
(At least in 25.1 and up; I don't have 24.4 here.)

In bug#16577, we discussed the possibility of adding more variables to
allow excluding files more easily.  If we had that, then adding "." and
".." to that would probably be pretty popular.

(So I'm merging this report with that report, because fixing it would
also fix this one.)
