Is there any way to "interrupt" a rebase?

Hi all,

When maintaining a long running branch, I regularly rebase onto our active development branch so that my branch stays up-to-date. What happens fairly often is that during such a rebase, Git will exit because of rebase/merge conflicts. Nothing unexpected there, of course, but as it sometimes turns out, the conflict should have been fixed in an earlier commit. The only way that I know of to fix this, is to abort the rebase and start over with "git rebase ... --interactive" then "edit" every commit and go through them one-by-one. This is often overkill, though. Is there a better way? Perhaps I could "rewind" the rebase to an earlier commit and restart from there?

So a scenario like this:

my-branch : X -> A -> B -> C -> D -> E -> F -> G base-branch : X -> Y

git rebase --onto base-branch HEAD~7 commit A --> conflicts ... lots of work ... commit B --> conflicts ... lots of work ... commit C (Git handles conflicts) commit D (no conflict) commit E --> conflicts ... er, that should have been fixed in commit C

How do I keep all the work I did for commits A and B? I get the impression that rerere does not help here because I did not finish the rebase succesfully (and that makes perfect sense, of course). Is there a way at this point in the rebase to "go back" to commit C (so without "git rebase --abort")?

(Surely, it's not as simple as doing a "git reset --hard sha-of-commit-C" is it?)

Cheers, Hilco
