What command did you invoke before hitting TAB?  Was that "C-x C-f" or
something else?

What version of Emacs is that?  Emacs already has "CVS/" in the value
of the variable `completion-ignored-extensions' (together with "./"
and "../", which you also see on your system), so it should ignore
those by default, unless they are the only files in the directory.
But some past versions of Emacs had a bug that would cause the
ignored directories to show anyhow.

What you ask in a) above already works for me in the CVS version of
Emacs; I'm not sure if Emacs 21.2 or 21.3 has that bug fixed, though.

I don't think it is a good idea to have such a feature: a user could
have in mind creation of a file in one of the empty directories on the
way down.
