This patch is a really good example of something that is very difficult
to review and see that there are no unintended changes.

Many people have complained about my patches, where I create a series of
many patches where each patch does exactly _one_ simple transformation to
the code. This is a good example _why_ I do that - a step by step single
transformation approach is way easier to review.

Sorry, but I'm not able to sensibly review this patch, and therefore
I won't apply it. Please split it into smaller changes.
