+T_SATIATION [-32768 to 32767]
+Set selected thing's satiation score. If above zero, and thing's lifepoints are
+below its thing type's initial lifepoints, there is a 1/32 chance each turn of
+waiting action that the thing's lifepoints will rise. Each turn, there is a
+chance of hitpoint loss that grows with the satiation score's absolute value.
+Each turn, T_SATIATION lessens by the square root of the thing's type's start
+hitpoints (see TT_LIFEPOINTS).
