Seems like that patch represents generally better coding practice,
and applying it would reduce cross-branch differences that would be
hazards for future patches, so I'm mostly +1 for this.

But I'd suggest waiting till after next week's releases.  If there
are any problems induced by this, we'd be more likely to find them
with another three months' time before it hits the wild.
