36 ** Check for Condition After a Move
37 **
38 ** Various ship conditions are checked. First we check
39 ** to see if we have already lost the game, due to running
40 ** out of life support reserves, running out of energy,
41 ** or running out of crew members. The check for running
42 ** out of time is in events().
43 **
44 ** If we are in automatic override mode (Etc.nkling < 0), we
45 ** don't want to do anything else, lest we call autover
46 ** recursively.
47 **
48 ** In the normal case, if there is a supernova, we call
49 ** autover() to help us escape. If after calling autover()
50 ** we are still in the grips of a supernova, we get burnt
51 ** up.
52 **
53 ** If there are no Klingons in this quadrant, we nullify any
54 ** distress calls which might exist.
55 **
56 ** We then set the condition code, based on the energy level
57 ** and battle conditions.
