Used by the routine at Place_Guardian.
Puts the rock formation of the type 136 (see Handle_Rock_Formation) in the room of a guardian, if the room is a cave.
The four object records that start at Object_Record_8 are cleared. The third one, at Object_Record_10, becomes the rock formation and has bit 0 of its redraw flags set, so that it is drawn.
