 > For whatever reason, on initialization, autosaveLast is getting assigned
 paragraph tags. I don't know why, but it does. And [24787] fixes it. I
 don't know why, but it does. Once autosave fires, autosaveLast is re-
 populated and it is no longer assigned paragraph tags, so subsequent
 autosave checks bail for lack of content changes.

 So... Upon further review, this isn't entirely right. aaroncampbell,
 markjaquith, and I are sometimes getting autosaveLast with paragraph tags,
 and sometimes without. We're all reproducing it at vastly different
 frequencies. (Meanwhile, duck_ still can't reproduce it.) All on Chrome
 (same version, some Linux, some Mac), also reproduced in Safari to some
 extent. (Not reproduced in Firefox at all.)
