RE: problem with "co -d xx -n" : bug or feature?

Sorry, I'm on the road at the moment and can't check my e-mail often, or the
CVS repository at all!  What you're describing seems very similar to the
patch I downloaded from cvshome.org (or it's previous incarnation) a year or
two ago.  If you can wait 3 weeks, I can check our repository when I get
home.  Otherwise, someone else may be able to help.  As I said previously,
there is (was?) a patch at one time to fix a bug similar to this.
