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.
