[PATCH v7 0/8] Fix scissors bug during conflict

This is a complete replacement for dl/merge-cleanup-scissors-fix.

Previous discussion on the cherry-pick/revert changes can be found here[1].

Changes since revert/cherry-pick v3:

* Rebased on top of latest master
* Reordered and squashed patches
* Added populate_opts_cb and save_opts to save default_msg_cleanup at Phillip's suggestion
