If I 'rm -rf' a directory that is part of a working copy directory,
and then do 'svn up', the missing directory gets replaced. It would
appear that the client is describing the missing directory to the
repository, and the repository is sending an update to reinstate it.
That appears to be something like what you have dscribed in (1) above,
and so I would have thought it was possible to get the repository to
send a delete, in the same way it sends an update. (Note, I haven't
examined the code, so I'm not claiming this will definitely work, just
that I think it might work.)
