Yes, but you're actually asking the question backwards -- you're asking
for the differences from the tip of the branch to the last tag rather
than from the last tag to the tip of the branch.  Since you're using
--brief it doesn't make any difference, but it would otherwise.

Right, because the last tag is not on the branch.  You should be able to
skip the diff and get what you want with just log:

        cvs -q log -S -r<last-tag>::<branch>
