interactive rebase results across shared histories

[Seb <spluque@gmail.com>]

Hello,

I've recently learnt how to consolidate and clean up the master branch's
commit history.  I've squashed/fixuped many commits thinking these would
propagate to the children branches with whom it shares the earlier parts
of the its history.  However, this is not the case; switching to the
child branch still shows the non-rebased (dirty) commit history from
master.  Am I misunderstanding something with this?

Thanks,
