FWIW I don't think that file-name-all-completions and file-name-completion
need to be changed at all in order to implement the PREDICATE argument
for read-file-name.
It might be convenient to do so, but if there really is a serious
issue with the file-name-handlers, we can always revert to implementing
the PREDICATE in read-file-name-internal (I have an elisp version
of it, if you prefer using that).
