Comment (by nacin):

 [attachment:16714.2.diff] has some problems in map_meta_cap(). Rather than
 mapping to 'edit_posts', it should map to
 `post_type_object->cap->edit_posts`.

 Bonus: It should instead map to `cap->create_posts`, and in
 get_post_type_capabilities(), `cap->create_posts` should be set to
 `'edit_' . $plural_base` by default, essentially mapping it on the fly to
 edit_posts.

 Both of these work only if we know the post type. So, we'll probably need
 to clarify that this can only be used like this:

 `if ( current_user_can( 'create_post', $post_type )` (or 'create_posts').

 If used directly, as in $post_type_object->cap->create_posts, then
 $post_type isn't necessary. Attached is my thought process so far.
