So I think the commit is fine, and yes, it should be applied to
stable, but it's one of those "there were three different patches in
as many days to fix the problem, and this is the right one, but maybe
stable should hold off for a while to see that there aren't any
problem reports".

I don't think there will be any problems from this, but while the
patch is tiny, it's conceptually quite a big change to something that
people haven't really touched for a long time.

So use your own judgement, but it might be a good idea to wait a week
before backporting this to see if anything screams.
