Just that I agree with you.  You can make a case that $Name$ should be
expanded only on release tags because only a release tag gives
unambiguous information as to what is being built.  Personally, I'd
rather have the information on branch tags as well;  if I misuse it,
that would be my problem.

Did you try "update -p" ?  I don't remember how it goes, but I think
that "cvs update -p dummyfile > dummyfile" expands the keyword.  It will
of course clobber any sandbox changes in dummyfile, so the use case
would be to keep dummyfile around just for its Name keyword, so the
built executable is able to identify itself.
