[If you try to add a directory with a CVS 1.9.24 (or so) client and a
CVS 1.9 server, you'll get a "cvs server: <dir> already exists, with
version number" error.

I've enclosed an attempted patch.  I'm not really sure whether it is
close or whether a fairly different approach is called for.  The patch
solves this particular problem but causes a testsuite failure in
modules2-10 (other relevant tests: errmsg2, basicb).
