Is there any way to "interrupt" a rebase?

[Hilco Wijbenga <hilco.wijbenga@gmail.com>]

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,
