I'd rather not have this miscount.  But it's easy to solve; it means
that when two directories have the same name, you have to check those
individually to see if they are directories so you can count links
correctly.

But that's not so bad.  It doesn't mean checking every single entry in
both directories; it means checking only those elements which are
duplicated names.
