Hi Denton

Fix a bug where the scissors line is placed after the Conflicts:
section, in the case where a merge conflict occurs and
commit.cleanup = scissors.
Note that the removal of the if-else tower in git_sequencer_config may
appear to be a no-op refactor but it actually isn't. First of all, we
now accept "default". More importantly, though, if
commit.cleanup = scissors, the cleanup enum will be set to
COMMIT_MSG_CLEANUP_SCISSORS instead of COMMIT_MSG_CLEANUP_SPACE when we
are reverting or cherry-picking. This allows us to append scissors to
MERGE_MSG in the case of a conflict.
