Elijah (added in Cc) has been working on "git merge-tree" improvements
based on the new "ort" merge he developed. It supports merging 2
branches, but maybe there are ways to make it support more than 2.

Yeah, I think that's what you want.

I don't know octopus merges much, but I think you should be able to
abort using "git reset" (maybe with "--hard"). If the merge was
performed using --no-commit or if there was a conflict, then I think
it should be expected that there is no MERGE_HEAD as no commit would
be created so MERGE_HEAD would have nothing to point to.
