41** Automatic Override
42**
43** If we should be so unlucky as to be caught in a quadrant
44** with a supernova in it, this routine is called. It is
45** called from checkcond().
46**
47** It sets you to a random warp (guaranteed to be over 6.0)
48** and starts sending you off "somewhere" (whereever that is).
49**
50** Please note that it is VERY important that you reset your
51** warp speed after the automatic override is called. The new
52** warp factor does not stay in effect for just this routine.
53**
54** This routine will never try to send you more than sqrt(2)
55** quadrants, since that is all that is needed.
