Wouldn't this be a slight regression, though?
We used to ignore an unsearchable directory but now we blindly say
"ah, it is a directory".
Checking is_directory() in addition to the existing access() would
be making a progress by fixing one bug (i.e. we no longer are
confused by an executable file there); skipping that access() based
on the filesystem quirks can be left for another day, of course.
