As best I can tell, this description is even further away from the
actual CVS HEAD behavior than the previous one.  The code is comparing
against

        anltuples = tabentry->n_live_tuples + tabentry->n_dead_tuples -
            tabentry->last_anl_tuples;

and deletions surely increase n_dead_tuples.
