Yes that's why I prefer using pasting the output of git log rather than bits of rebase-merge/done into the todo list when rewinding manually. > > (This all would of course only work properly without --preserve-merges and > without the upcoming --recreate-merges.) It shouldn't be too hard to support --recreate-merges in the case where you don't go past a merge commit, one would just have to check refs/rewritten to see if any label commands need to be inserted.
