Indeed, because it forces a test to be _not_ on the symlink but on what
is on the far side of it.

BTW, if you've been following this thread you should know that:

  [^.]*/

is better written:

  */

which means _exactly_ the same thing.

Of course, you realise that you may not need to test for -d at all
because */ will only return directories (or things pointing at them).
(Except when there are no directories at all - the it returns "*/"
unchanged and you just need to test for existence.)
