Leave out empty (pointless) commits during rebase

I don't think I follow, as far as I know after rebasing B' and C', you would end up with:

---A----A'
              \
               B'----C'

That's the way it works here at least.

I have attached a shell script that hopefully shows what I mean. If you rebase C onto A', the branches B' and C' diverge.

And, by the way:
