change the comment, warren says we can ignore what RH wants here, and
https://bugzilla.ubuntu.com/show_bug.cgi?id=4538 asks that we follow
gnome's HIG here. its a trivial little change that only people with a
desktop environment (vrs just a wm) will see, so I don't really mind
following the gnome hig here
someone may be able to think of better wording.
