The '-P' flag (prune) suppresses empty directories in the update.

I have no problem with that. I think this situation is unsatisfactory,
though, I'll have to cvs-update my source repository in two, maybe three
separate steps, to avoid checking everything out _again_.

Alastair: Thanks a lot for the detailed reply! I'll take a look at the
build again; maybe I can get this problem fixed after all.
