More generally, shouldn't the READ-DIR argument specify constraints on
the desired file type? For example, in many instances you want a
non-directory.
How about allowing READ-DIR to be any predicate, so that the invoker
of read-file-name can filter file names in arbitrary ways? I suspect
that this would subsume read-file-name's existing MUSTMATCH argument
to some extent, since MUSTMATCH=t would be roughly equivalent to
READ-DIR=file-exists-p, but I can't think of a cleaner extension
offhand.
