I was hoping for a rebase that recalled what your previous base commit of your branch.

I'm really not fond of having to `git rebase --interactive` just to drop all commits that are "already in master", especially when I forget this silly step and get a borked rebase.

Does this not do what you want?

    git rebase -i master..HEAD
