I do not think --abort was designed to abort an uncontrolled stop
like ^C in the first place.  To allow that kind of "recovery", you
need to teach "rebase" to first record the state you would want to
go back to before doing anything, but then what happens if the ^C
comes when you are still in the middle of doing so?
