FWIW, I'm not on board with reordering system-header inclusions.
Some platforms have (had?) ordering dependencies for those, and where
that's true, it's seldom alphabetical.  It's only our own headers
where we can safely expect that any arbitrary order will work.

I would take out the blank lines between our own #includes.  Those are
totally arbitrary and unnecessary.  The whole point of style rules like
this one is to reduce the differences between the way one person might
write something and the way that someone else might.  Deciding to throw
in a blank line is surely in the realm of unnecessary differences.
