 I just wanted to remove stale contenttypes from a system and noticed a
 pretty significant bug.

 The command prints a message before you need to confirm the deletion that
 reads:
 > This list doesn't include any cascade deletions to data outside of
 Django's models (uncommon).

 However, a quick investigation on the objects that are to be deleted
 includes objects outside of Django's scope.
 In my case:

 >    - 2 auth.Group_permissions object(s)
 >    - 7185 joeflow.Task object(s)
 >    - 5519 joeflow.Task_parent_task_set object(s)

 This misinformation can cause users to delete data without double-
 checking.
