Why is this closed without actually landing? I shortened the title a bit - it
complained...

Something weird happened here. Apparently rietveld disallows writing messages to
CLs with a title longer than 100 chars. So the CQ couldn't write either -
therefore I didn't see that this actually landed.

On the console view of buildbot this change is now omitted. This might be a
weird feature?
