Challenge

Have you tried a literature search? --prime mover (talk) 19:05, 10 February 2013 (UTC)
I asked over at stackexchange, and someone sketched a choice-free proof. It's a bit on the gappy side, but it looks like it probably works. I'll get to filling in gaps to make a second proof. --Dfeuer (talk) 14:19, 12 February 2013 (UTC)
