The merge command of svndumptool can do the "reparenting" of subtrees. I
guess deleting subtrees wouldn't be hard to add to it. But when copy-from
references a deleted node there are two cases: Either the copied node has
to be deleted too or the copy has to be transformed into a normal add
which then needs the text of the copy-from node (which is not available
anymore when processing a stream).

Hmm, I guess that's why I never implemented delete...
