I agree that we need some way to implement read-directory-name,
but I find those functions with never-ending lists of arguments
rather annoying and would rather not add yet-another-one.

The "somehow" part is rather interesting.  A seemingly trivial way
would be to use the `predicate' argument passed to completing-read
(and then to read-file-name-internal), except that that argument is
already (ab)used to pass the current-directory to use when completing.
