Yes, `cvs -n update' will list these as "new directory" as if `cvs update'
would bring them in.  Problem is, `cvs update' would not bring them in
if you use the `-P' option (which is generally recommended).

In other words, the problem is that `cvs -n update' ignores the `-P'
option.  It's difficult for PCL-CVS to fix it, and I couldn't
find a trivial fix in CVS itself either (although that doesn't say
much because I'm very non-familiar with the code).

One solution is to not use the `-P' option, of course.

PS: In earlier versions of PCL-CVS those messages were not turned into
    `Need-Update' but into mere informational messages.  Such messages
    are less annoying in your case, but `Need-Update' is the right
    thing to do in the case of a true new directory.
    The only solution I can think of is to make it a user-option,
    which is rather a cop-out.

CVS/Entries.Log contains the list of deleted directories.
Maybe you could use it to filter out this junk altogether?

Hmm... that would be awesome, but I can't find any such file here.

work/emacs-1% echo **/CVS/Entries.*
zsh: no match
work/emacs-1% 

And CVS' info page indicates that Entries.Log is transient
and only used to deal with failure-during-update.

ouch.

maybe you could report this as a bug to the CVS maintainers?
maybe you could even patch the cvs client to respect -P with -n?

Emacs is a sufficiently important application for the CVS people to
accommodate us.

It's a known bug.  Feel free to try and fix it but:
1 - it's not trivial to fix.
2 - CVS maintainers don't take patches very gladly in my experience.
    At least I had trouble getting them to cooperate into bringing my
    patches to a good enough state.

I.e. I have better things to do.

They may very well disagree,
