Yes, thanks, the code LGTM now.

You know that the predicate will be ignored when MUSTMATCH is t?
The behavior is not different than for `read-file-name'.

I think your patch is definitely a step in the right direction, but I
also still think we should think about the semantics of the restricting
arguments as a whole.
