  13  * The running algorithm:                       -CJS-
  14  *
  15  * In the diagrams below, the player has just arrived in the
  16  * grid marked as '@', and he has just come from a grid marked
  17  * as 'o', and he is about to enter the grid marked as 'x'.
  18  *
  19  * Of course, if the "requested" move was impossible, then you
  20  * will of course be blocked, and will stop.
  21  *
  22  * Overview: You keep moving until something interesting happens.
  23  * If you are in an enclosed space, you follow corners. This is
  24  * the usual corridor scheme. If you are in an open space, you go
  25  * straight, but stop before entering enclosed space. This is
  26  * analogous to reaching doorways. If you have enclosed space on
  27  * one side only (that is, running along side a wall) stop if
  28  * your wall opens out, or your open space closes in. Either case
  29  * corresponds to a doorway.
  30  *
  31  * What happens depends on what you can really SEE. (i.e. if you
  32  * have no light, then running along a dark corridor is JUST like
  33  * running in a dark room.) The algorithm works equally well in
  34  * corridors, rooms, mine tailings, earthquake rubble, etc, etc.
  35  *
  36  * These conditions are kept in static memory:
  37  * find_openarea         You are in the open on at least one
  38  * side.
  39  * find_breakleft        You have a wall on the left, and will
  40  * stop if it opens
  41  * find_breakright       You have a wall on the right, and will
  42  * stop if it opens
  43  *
  44  * To initialize these conditions, we examine the grids adjacent
  45  * to the grid marked 'x', two on each side (marked 'L' and 'R').
  46  * If either one of the two grids on a given side is seen to be
  47  * closed, then that side is considered to be closed. If both
  48  * sides are closed, then it is an enclosed (corridor) run.
  49  *
  50  * LL           L
  51  * @@x          LxR
  52  * RR          @@R
  53  *
  54  * Looking at more than just the immediate squares is
  55  * significant. Consider the following case. A run along the
  56  * corridor will stop just before entering the center point,
  57  * because a choice is clearly established. Running in any of
  58  * three available directions will be defined as a corridor run.
  59  * Note that a minor hack is inserted to make the angled corridor
  60  * entry (with one side blocked near and the other side blocked
  61  * further away from the runner) work correctly. The runner moves
  62  * diagonally, but then saves the previous direction as being
  63  * straight into the gap. Otherwise, the tail end of the other
  64  * entry would be perceived as an alternative on the next move.

  71  *
  72  * Likewise, a run along a wall, and then into a doorway (two
  73  * runs) will work correctly. A single run rightwards from \@ will
  74  * stop at 1. Another run right and down will enter the corridor
  75  * and make the corner, stopping at the 2.

  82  *
  83  * After any move, the function area_affect is called to
  84  * determine the new surroundings, and the direction of
  85  * subsequent moves. It examines the current player location
  86  * (at which the runner has just arrived) and the previous
  87  * direction (from which the runner is considered to have come).
  88  *
  89  * Moving one square in some direction places you adjacent to
  90  * three or five new squares (for straight and diagonal moves
  91  * respectively) to which you were not previously adjacent,
  92  * marked as '!' in the diagrams below.

  96  *   ...!  (east)      ..@@!  (south east)
  97  *                      !!!
  98  *
  99  * You STOP if any of the new squares are interesting in any way:
 100  * for example, if they contain visible monsters or treasure.
 101  *
 102  * You STOP if any of the newly adjacent squares seem to be open,
 103  * and you are also looking for a break on that side. (that is,
 104  * find_openarea AND find_break).
 105  *
 106  * You STOP if any of the newly adjacent squares do NOT seem to be
 107  * open and you are in an open area, and that side was previously
 108  * entirely open.
 109  *
 110  * Corners: If you are not in the open (i.e. you are in a corridor)
 111  * and there is only one way to go in the new squares, then turn in
 112  * that direction. If there are more than two new ways to go, STOP.
 113  * If there are two ways to go, and those ways are separated by a
 114  * square which does not seem to be open, then STOP.
 115  *
 116  * Otherwise, we have a potential corner. There are two new open
 117  * squares, which are also adjacent. One of the new squares is
 118  * diagonally located, the other is straight on (as in the diagram).
 119  * We consider two more squares further out (marked below as ?).
 120  *
 121  * We assign "option" to the straight-on grid, and "option2" to the
 122  * diagonal grid, and "check_dir" to the grid marked 's'.
 123  *
 124  * \#\#s
 125  * @@x?
 126  * \#.?
 127  *
 128  * If they are both seen to be closed, then it is seen that no benefit
 129  * is gained from moving straight. It is a known corner.  To cut the
 130  * corner, go diagonally, otherwise go straight, but pretend you
 131  * stepped diagonally into that next location for a full view next
 132  * time. Conversely, if one of the ? squares is not seen to be closed,
 133  * then there is a potential choice. We check to see whether it is a
 134  * potential corner or an intersection/room entrance.  If the square
 135  * two spaces straight ahead, and the space marked with 's' are both
 136  * unknown space, then it is a potential corner and enter if
 137  * find_examine is set, otherwise must stop because it is not a
 138  * corner. (find_examine option is removed and always is TRUE.)
