$notice instead of $multi
https://gerrit.wikimedia.org/r/#/c/73014/ breaks JavaScripts that use class='diff-multi' to identify multi diffs because the class get set when there is not multi diff but a empty diff.
Suggested solution: Use a separate table row for diff-empty.
The attached patch uses $notice instead of $multi. A new table row would be an other way.
