Comment (by azaozz):

 dont-save-autosave.diff won't work as expected (and has a copy/paste typo,
 `$new_data` is not defined in `wp_create_post_autosave()`).

 It only checks whether the autosave is the same as the current post when a
 previous autosave exists. To catch the first autosave, perhaps we can move
 the test for changed fields from `wp_save_post_revision()` to
 `_wp_put_post_revision()`. We will still need the same test in
 `wp_create_post_autosave()` for the cases when an autosave is updated.
