. and foo/. are also links, not directories... the directories themselves 
are filesystem internal objects, and not discussed by the standard.  I 
didn't know that linux supported hard links to directories... Isn't that 
just asking for trouble?

It rarely hurts to violate even a written standard when it says something 
like this...  If it says something like this (which can only happen 
intentionally, afaict) should fail, but you can do something intelligent 
instead, you probably should.
