The possibility is to dump your repository, edit it (maybe by tools),
and create a new repository from it.

As I (tried to) say in my other email: either way is fine with me (not
that I matter much). I care more about the ease of the UI than the
implementation. I brought up implementation issues only because I
thought avoiding repos syncs maybe would be the easier way to get a
solution to the use cases.

Well, having had some days to let sink it in, I think the local-repo
option has a more realistic chance to become implemented, as any
change to libsvn_wc (and my suggestion would need those), will have a
hard time to be accepted.

Well, since both our ideas would benefit from a specification of
history diffs, we could take a step back and start with creating some
