Pass-through handling (again) in tovmsspec.

This is a partial retreat from b3efb2487fa7, where we started
passing through all ambiguous filespecs without modification. We
can now process the majority of cases that aren't macros, following
59247333b91 and various other commits that improved the escaping
of dots.  So for now we'll attempt to process these and pass
through macros only.
