Add a missing anchor for "new" copied files in the diff viewer.
Review Request #7384 — Created June 5, 2015 and submitted — Latest diff uploaded
Files that were marked both as "new" and also copied from another file were missing an anchor, causing the file index to fail. This is pretty rare, so it wasn't reported before, but we had a case where it happened just recently. We should now have an anchor in all cases.
Tested with a file in this state. Saw the anchor. Clicking the file index
took me there.
