Here is the same patch with a slight modification: capped the usefullness 
of the city by 0 if it has food or shield deficit:

int ai_eval_calc_city(struct city *pcity, struct ai_data *ai)
{
  int i = (pcity->food_surplus * ai->food_priority
           + pcity->shield_surplus * ai->shield_priority
           + pcity->luxury_total * ai->luxury_priority
           + pcity->tax_total * ai->gold_priority
           + pcity->science_total * ai->science_priority
           + pcity->ppl_happy[4] * ai->happy_priority
           - pcity->ppl_unhappy[4] * ai->unhappy_priority
           - pcity->ppl_angry[4] * ai->angry_priority
           - pcity->pollution * ai->pollution_priority);
  
  if (pcity->food_surplus < 0 || pcity->shield_surplus < 0) {
    /* The city is unmaintainable, it can't be good */
    i = MIN(i, 0);
  }

  return i;
}

I will commit the patch soon unless discontent citizens prevent me from 
doing so.
