<Someone> (also later forwarded by <Someone>) reported that choking
while eating non-food always resulted in calling it a "quick snack".
lesshungry() depends on an occupation to tell if you are actually eatig or
not, but since non-food is eaten in one turn, no occupation was set. Took
his suggestion of setting the occupation temporarily to cause lesshungry()
call choke() appropriately in this case.
