So how would I best review this?

I applied the patches locally[1], and ran git-ls-tree on this commit
hoping to find the same blob id for git-rebase--interactive.sh as for
git-rebase--preserve-merges.sh; however I did not.

So I diffed them and had the diff below[2], which looks like that has parts
of Johannes recent series?

Thanks,
Stefan
