You should better did this step prior to commiting 1.2, as this is
just adding points of failure...

You have to choose 1.1 and 1.1.2.1!
Or better yet, just choose 1.1.2.1 as "start" and let cvs find the
latest mergepoint for you.
When you select two revisions for merge, you're telling cvs "merge the
differences between these two revisons into my working copy". Since
you started your branch off of 1.1, the difference between them is 1.2
-> 1.1 -> 1.1.2.1 (i.e. it will undo the changes made in 1.2)
