The problem I'm having with this is that with a `git rebase -p -i master` I can't even squash two related changes that are right next to each other together because the rebase bails out earlier on conflicts while trying to replay.

I think that's easier said than done, with backend work I'm able to clearly define topics, whereas the front-end developers (as it is in this case) typically overlap ever so slightly in their work Cheers, -R.
