I think there are different minds on this; I *generally* prefer pure
code movement to be with as few changes as possible, to make sure actual
changes are easy to call out.

The changes you've asked for are pretty minor (and you're the maintainer
of the file it's being moved to), so I won't argue about it in this
particular case.  Just want to counter the idea that move + change is
the norm. :-)
