Hi Alexander, I think I had similar feedback earlier, but these would be reviewable more easily if these three unrelated things are broken up into three separate patches.

Hi Vishal, You did ask me to add more details into commit message and possibly split the patch. I've added the details, but about the second I pleaded to save few hours of my time on reshuffling trivial patches. Apparently my plea was not good enough. Apparently you have a long line of people who wish to fix this area. Whatever, doing it now, hopefully to end this and focus on things that actually matter. > A few other minor comments below.
