I'm not sure what exactly what information you're asking for?

It just works. I mean, you still can get conflicts when you merge back and you
resolve those just as you normally would.

Thinking about it, I guess you might have to redo conflict resolution again when
you merge changes back to trunk.

I guess if svnmerge did a diff between the pristine merge to the branch and what
was committed, then applied that back to the trunk, that would be a nice
addition, and presumably, would reduce merge conflicts on the trunk.
