Pardon me if I ask a silly question, but how could a single revision be
present on multiple branches? As far as I understood the revision number
exactly defines where the revision belongs to, doesn't it?

I agree that my suggestion of HEAD as described above is not so necessary as
a pseudo-branch-tag for the main trunk (be it called TRUNK or MAIN - as Noel
suggested - or some other meaningful name).
I freely admit that my suggestions were made from a users point of view.
Although I did some modifications in WinCVS that also took me inside the CVS
code, I am far from having insight into the huge CVS sources and their
numerous interactions. So I could only hope that someone with enough
knowledge would implement the tags if they were found useful. In my humble
personal opinion at least TRUNK is.
Best regards
