I am getting "more benevolent", but the patch should be there for at
least some good reason. This one was picked by the "semi-automatic"
checker, and at first glance seems like it is a real bugfix. But, as
you mention, it was only needed in preparation for a future patch, then
this patch is not needed in the stable trees, and I'll go drop it now.
