Introduce a new "git cherry-pick --continue" command which uses the information in ".git/sequencer" to continue a cherry-pick that stopped because of a conflict or other error. It works by dropping the first instruction from .git/sequencer/todo and performing the remaining cherry-picks listed there, with options (think "-s" and "-X") from the initial command listed in ".git/sequencer/opts". So now you can do: $ git cherry-pick -Xpatience foo..bar ... description conflict in commit moo ... $ git cherry-pick --continue error: 'cherry-pick' is not possible because you have unmerged files. fatal: failed to resume cherry-pick $ echo resolved >conflictingfile $ git add conflictingfile && git commit $ git cherry-pick --continue; # resumes with the commit after "moo" During the "git commit" stage, CHERRY_PICK_HEAD will aid by providing the commit message from the conflicting "moo" commit. Note that the cherry-pick mechanism has no control at this stage, so the user is free to violate anything that was specified during the first cherry-pick invocation. For example, if "-x" was specified during the first cherry-pick invocation, the user is free to edit out the message during commit time. Note that the "--signoff" option specified at cherry-pick invocation time is not reflected in the commit message provided by CHERRY_PICK_HEAD; the user must take care to add "--signoff" during the "git commit" invocation.
