No. It's supposed to only show differences your patch makes. The test is
pretty mean though. I wouldn't take this as regression. Just ignore it.

The test case is pretty academical anyway :)

If it was broken before, it's no regression. If you have a fix for cl2, even better.

Yes.

Because the bug was about something else. We can't leave all bugs open
that aren't rendered perfectly. Usually we open a new bug report with
a more specific description + test case.

If you improve the splits, this would be fine. Otherwise I'll just commit as it
is unless someone objects.
