Used by the routine at WINDOW_OTHERS.
The exit that goes through the object; refused if there is none, if it leads nowhere yet, or if the object will not let anyone through (CAN_PASS). Otherwise it is a move in that exit's direction, into MOVE past its darkness and captivity checks. GO_BY_EXIT is the way in for callers that have found the exit already.
