If things work like we want, the changes will have to end up in trunk.
That's not to say you can't work in a git branch. One concern I have is
pulling between git repos that have been rebased to svn, as I understand it
this can lead to problems. OTOH, I think things should work if both git
repos are rebased to the same svn revision. Hmm, it might be best to work in
a branch that is kept rebased to the master which is kept in sync with svn.
Maybe someone who knows a bit more about git can weigh in here.
