My vote is to not make this sort of change until there's another
reason to touch the code in question. All changes create hazards for
back-patching, and I don't think this change is worth it on its own.
But if there are going to be diffs in the immediate vicinity anyway,
then sure.
(I'm feeling a bit sensitized to this, perhaps, because of recent
unpleasant experience with back-patching b4570d33a. That didn't touch
very much code, and the functions in question seemed like fairly stagnant
backwaters of the code base, so it should not have been painful to
back-patch ... but it was, because of assorted often-cosmetic changes
in said code.)
