I think this probably makes sense.

Should this be mentioned in the comment documenting OPT_FILENAME()?

I thought at first this needed a final "else" clause, because we don't
assign to *file if we have neither a prefix nor a user-path. But that's
what the callers expect (and we are similarly a noop if we hit the first
conditional). So this looks right.
