45 ** Automatic Override
46 **
47 ** If we should be so unlucky as to be caught in a quadrant
48 ** with a supernova in it, this routine is called. It is
49 ** called from checkcond().
50 **
51 ** It sets you to a random warp (guaranteed to be over 6.0)
52 ** and starts sending you off "somewhere" (whereever that is).
53 **
54 ** Please note that it is VERY important that you reset your
55 ** warp speed after the automatic override is called. The new
56 ** warp factor does not stay in effect for just this routine.
57 **
58 ** This routine will never try to send you more than sqrt(2)
59 ** quadrants, since that is all that is needed.
