I saw your blog entries on this topic... not much time to reply right
now, but basically there are 2 ways that people address this problem.

One way is to do merges, either using cvs commands (which is a little
tricky, and means tagging the branch-from-which-the-merge-comes at
merge time so that subsequent merges start at the right place).  This
is probably in a cvs cookbook somewhere.  Another way is what Andrew
H. apparently uses (I never asked :-), namely generating patches by
hand and applying them to the branch.  Kind of painful.

The other way is to just give up and make a new branch.  This was
pretty common in gcc land.  Actually in gcc land people did evil
things involving moving branch tags (this lets you re-branch but keep
the old branch name).  I'd prefer we not do that though.

svn (or really any newer VC system) is definitely nicer for this sort
of thing.
