I've looked at the patches up to this point. The ones I did not
comment (including this one ;-) looked perfect, and all of them
(including the ones I did comment) were cleanly described to easily
read the reasoning behind these changes, which I highly appreciated.
Especially if I did not quite agree with the reasoning, it helped me
clarify my thought where I found it not agreeable.
Thanks.
