I agree. I would really like a way to replace the idioms

  cvs tag foo-bp
  cvs tag -b foo-branch
  cvs up -r foo-branch
  .....lots of changes and commits....
  cvs diff -rfoo-bp -rfoo-branch

with something like:

  cvs tag -b foo-branch
  cvs up -r foo-branch
  .....lots of changes and commits....
  cvs diff -rfoo-branch.root -rfoo-branch

so that we don't need lots of foo-bp tags in the tree.

The possibility of doing something like this:

  cvs tag -b -rfoo-branch.root foo-redeux-branch

to allow the creation of an alternative implementation of modified code
based on the same original baseline version as foo-branch would also be
interesting.

Yes, it would be highly desirable to be able to do

   cvs udpate -j.commitid.XXX  -j.commitid.XXX.prev

to reverse a particular patch.
