Can someone apply and push this one? It was approved by Marcus yesterday,
but since I can't push it myself, the ChangeLog has gotten another
conflicting entry now - so whoever applies it will have to fix it up. (I
won't try to send a new resolved patch because someone else will probably
touch the ChangeLog inbetween again, before someone gets to pushing it.)
