That is an impressively convoluted and confusing Subject...

This seems rather invasive - not sure if this could have been reasonably
broken down into smaller pieces...

OK.

I also dealt with the massive amount of whitespace / coding style crap in
your patch. I keep doing that and keep hoping that you at some point will
look at the modifications that I make or at the notes in CodingStyle.
We have settings for many of the common editors. Is there a reason why
your patches always are so much work to apply?
