This fixes a bug where the scissors line is placed after the Conflicts:
section, in the case where a merge conflict occurs and
merge.cleanup = scissors.
Next, if commit.cleanup = scissors is specified, don't produce a
scissors line in commit if one already exists in the MERGE_MSG file.
Finally, we give pull the passthrough option of --cleanup so that it
can also take advantage of this change.
