While I'm not necessarily objecting to the content of this patch,
I do have a problem with the process. Where was the discussion of
why this change should be back-patched? (If I'm identifying it
correctly, this is a back-patch of commit bd56e7412, a year and a
half later. That should have been noted in the commit message, too,
rather than leaving people to reconstruct why you'd only committed
into two old branches.)
