 Hmm, I guess I assumed the struct for custom fields was the same for
 wp.editPost() and wp.newPost(), apparently not. That's what I get for
 assuming.

 This kind of situation where there's accurate docs in the Codex and
 basically none in the source makes me wonder what else is missing
 elsewhere. It also leads me to commend @maxcutler or whomever wrote the
 original Codex article for this method.
