Pass $post_id as second argument to delete_postmeta action
|Reported by:||Vynce||Owned by:|
in every case (in WP 3.2) where a postmeta is deleted, the context is aware of the post_id or post_ids affected. The do_action calls for added_postmeta, update_postmeta, and updated_postmeta all pass the post_id as the second argument. For parallelism, and because it is useful, please pass it for delete_postmeta (and deleted_postmeta).
