Exact equivalent of `git rebase --onto ancient origin/ancient modern` ? about git-imerge

As you know, git-imerge doesn't have the equivalent of the --onto option.

If I understand your use case correctly, the end effect of your multiple rebases would be the rebase of a full branch, which, if you did it directly, wouldn't need the --onto option. You only need the --onto option because you want to preserve some checkpoints. Is that correct?

If so, then IMO the correct solution to this problem would be for you to run a full git imerge rebase, but for git-imerge to make it possible to interrupt such a rebase while it is in progress even if it hasn't been completed. For example, see #101. That way you wouldn't need to do any additional manual bookkeeping but could still stop if you get stuck.
