There are a few entries particularly at the end of the file that aren't
in order. To avoid confusion, add a comment that might help new entries
to be added in the right place.

I think it's ok if it avoids review comments that new entries should be sorted. Or maybe we do the opposite and the comment should say this file is allowed to be unsorted...
