Changes (by scribu):

  * keywords:  post__in, category__in, tag__in, tag_slug__in,
               fill_query_vars, array_keys, get_posts =>
               needs-patch
  * milestone:  2.9.2 => 3.0


Comment:

 I think a better solution would be for fill_query_vars() to fill post__in
 with 'false' or 'null' rather than not setting it at all.
