Comment (by adamsilverstein):

 in [attachment:7392.2.diff​ 7392.2.diff​]:
 * add duplicate content check in wp_create_post_autosave, refreshed from
 [attachment:7392-autosave.patch 7392-autosave.patch]
 * note that if "revisioned fields" (by default: title, content, excerpt)
 are unchanged, autosaves will not fire, even if you change revisioned
 post_meta such as post format. (also true of regular update revisions)
