Fixed #9946 -- Removed redundant mention of needing to define `list_display`.

        list_display = ('first_name', 'last_name', 'birthday')

        list_display_links = ('first_name', 'last_name')

Finally, note that in order to use ``list_display_links``, you must define

``list_display``, too.

``list_editable``
