Comment (by helen):

 [attachment:35598.4.diff] seems like a solid change to me, and a quick
 look around plugins leads me to believe it's a safe change. Wish I'd had
 this the last time I was debugging a `wp_mail()` problem :) It's kind of
 an enhancement in some ways I suppose, but still a bug fix, so going in.
 If there's something still lacking with the tests, that can be corrected
 at any time.
