                [smc]  I just tried it.

                echo x > x
                cvs add x
                cvs commit -m x x
                cvs tag one x
                echo 2 >> x
                cvs commit -r 2.1 -m x x
                cvs diff -r one -r1 x
                (no output, that is, the diffs between rev 1.1 and rev 1.1 )
                cvs diff -r one -r.trunk x
                (you get the diffs between rev 1.1 and rev 2.1)

                I'll be adding such a case to sanity.sh in my patch later.

                (Does this justify the effort?  who am I to say?)
