44 ** Check for Condition After a Move
45 **
46 ** Various ship conditions are checked. First we check
47 ** to see if we have already lost the game, due to running
48 ** out of life support reserves, running out of energy,
49 ** or running out of crew members. The check for running
50 ** out of time is in events().
51 **
52 ** If we are in automatic override mode (Etc.nkling < 0), we
53 ** don't want to do anything else, lest we call autover
54 ** recursively.
55 **
56 ** In the normal case, if there is a supernova, we call
57 ** autover() to help us escape. If after calling autover()
58 ** we are still in the grips of a supernova, we get burnt
59 ** up.
60 **
61 ** If there are no Klingons in this quadrant, we nullify any
62 ** distress calls which might exist.
63 **
64 ** We then set the condition code, based on the energy level
65 ** and battle conditions.
