Hello, I frequently run an interactive rebase to change the order of recent commits, apply fixups, etc. When merge conflicts occur I often want to compare the result with the original head prior to starting the rebase. In the past I used "git diff ORIG_HEAD". This used to work as long as I did not manually invoke "git reset" during the operation. Since git version 2.20.1 (not sure, maybe 2.20.0?) this no longer works because ORIG_HEAD seems to get modified by fixup commits during rebase. Now I have to search through reflog to find the commit I want to compare the current head to. During the rebase operation the original head seems to get stored in 'rebase-merge/orig-head'. Unfortunately this references gets removed after the rebase operation completes. Would it be possible to retain this information? Could you set ORIG_HEAD back to rebase-merge/orig-head after rebase completes? Alternatively, could something like REBASE_HEAD be added for this purpose? Undoing a rebase would be related to this and is a very popular question on SO [1]. Users recommend using "git reset --hard ORIG_HEAD" which now no longer works.
