This patch doesn't touch those includes -- it only touches the ones at
the top of a file.  If you want to land yours first, it's no trouble for
me.  The change is just running a script.

On irc the other day, Simon had the idea that I could land the patch in
pieces: say, convert [a-f]*, test that, check it in.  I modified my
script to let me do this and the first batch went through.  So, if you'd
really rather this go first, let me know and I can do it that way.  It
may take a few days to get it all in.
