The abstract idea of tying ships and land units to a logistical tether is sound, the concrete implementation as option FUEL is flawed. It adds too much busy-work to the game to be enjoyable. It hasn't been enabled in a public game for years. The code implementing it is ugly, repetitive, and a burden to maintain. Remove selector fuel from ship_ca[] and land_ca[], and selectors fuelc, fuelu from mchr_ca[] and lchr_ca[]. Remove fields fuelc, fuelu from ship.config and land.config. Remove command fuel from player_coms[]. Deprecate edit key 'B' in doship(), dounit(), and don't show it in pr_ship(), pr_land(). Drop opt_FUEL code from build_ship(), shi(), sdump(), ship_damage(), show_ship_stats(), do_mob_ship(), nav_ship(), build_land(), land(), ldump(), land_damage(), show_land_stats(), do_mob_land(), resupply_all(), resupply_commod(), get_minimum(), has_supply(), unit_list(), vers(). Remove opt_FUEL, fuel_mult, struct shpstr member shp_fuel, struct mchrstr members m_fuelc and m_fuelu, M_OILER, struct lndstr member lnd_fuel, struct lchrstr members l_fuelc and l_fuelu, fuel(), and auto_fuel_ship().
