Note that filelib:is_file/1 and ls_file/1 is only called if file:list_dir/1

The first clause of ls_file/1 will be taken if File is either a
regular file or a directory that cannot be listed (e.g. because
of insufficient permissions).

The second clause will only be taken if File is a device or some
other sort of special file.

I don't know for sure Bengt's intention, but to me it makes
more sense if the first clause would only be taken if File is
a regular File.

This is probably a moot point if the patch is rewritten the
way I suggested.
