/*
 * The running algorithm:                       -CJS-
 *
 * In the diagrams below, the player has just arrived in the
 * grid marked as '@', and he has just come from a grid marked
 * as 'o', and he is about to enter the grid marked as 'x'.
 *
 * Of course, if the "requested" move was impossible, then you
 * will of course be blocked, and will stop.
 *
 * Overview: You keep moving until something interesting happens.
 * If you are in an enclosed space, you follow corners. This is
 * the usual corridor scheme. If you are in an open space, you go
 * straight, but stop before entering enclosed space. This is
 * analogous to reaching doorways. If you have enclosed space on
 * one side only (that is, running along side a wall) stop if
 * your wall opens out, or your open space closes in. Either case
 * corresponds to a doorway.
 *
 * What happens depends on what you can really SEE. (i.e. if you
 * have no light, then running along a dark corridor is JUST like
 * running in a dark room.) The algorithm works equally well in
 * corridors, rooms, mine tailings, earthquake rubble, etc, etc.
 *
 * These conditions are kept in static memory:
 * find_openarea         You are in the open on at least one
 * side.
 * find_breakleft        You have a wall on the left, and will
 * stop if it opens
 * find_breakright       You have a wall on the right, and will
 * stop if it opens
 *
 * To initialize these conditions, we examine the grids adjacent
 * to the grid marked 'x', two on each side (marked 'L' and 'R').
 * If either one of the two grids on a given side is seen to be
 * closed, then that side is considered to be closed. If both
 * sides are closed, then it is an enclosed (corridor) run.
 *
 * LL           L
 * @x          LxR
 * RR          @R
 *
 * Looking at more than just the immediate squares is
 * significant. Consider the following case. A run along the
 * corridor will stop just before entering the center point,
 * because a choice is clearly established. Running in any of
 * three available directions will be defined as a corridor run.
 * Note that a minor hack is inserted to make the angled corridor
 * entry (with one side blocked near and the other side blocked
 * further away from the runner) work correctly. The runner moves
 * diagonally, but then saves the previous direction as being
 * straight into the gap. Otherwise, the tail end of the other
 * entry would be perceived as an alternative on the next move.
 *
 * #.#
 * ##.##
 * .@x..
 * ##.##
 * #.#
 *
 * Likewise, a run along a wall, and then into a doorway (two
 * runs) will work correctly. A single run rightwards from @ will
 * stop at 1. Another run right and down will enter the corridor
 * and make the corner, stopping at the 2.
 *
 * ##################
 * o@x       1
 * ########### ######
 * #2          #
 * #############
 *
 * After any move, the function area_affect is called to
 * determine the new surroundings, and the direction of
 * subsequent moves. It examines the current player location
 * (at which the runner has just arrived) and the previous
 * direction (from which the runner is considered to have come).
 *
 * Moving one square in some direction places you adjacent to
 * three or five new squares (for straight and diagonal moves
 * respectively) to which you were not previously adjacent,
 * marked as '!' in the diagrams below.
 *
 *   ...!              ...
 *   .o@!  (normal)    .o.!  (diagonal)
 *   ...!  (east)      ..@!  (south east)
 *                      !!!
 *
 * You STOP if any of the new squares are interesting in any way:
 * for example, if they contain visible monsters or treasure.
 *
 * You STOP if any of the newly adjacent squares seem to be open,
 * and you are also looking for a break on that side. (that is,
 * find_openarea AND find_break).
 *
 * You STOP if any of the newly adjacent squares do NOT seem to be
 * open and you are in an open area, and that side was previously
 * entirely open.
 *
 * Corners: If you are not in the open (i.e. you are in a corridor)
 * and there is only one way to go in the new squares, then turn in
 * that direction. If there are more than two new ways to go, STOP.
 * If there are two ways to go, and those ways are separated by a
 * square which does not seem to be open, then STOP.
 *
 * Otherwise, we have a potential corner. There are two new open
 * squares, which are also adjacent. One of the new squares is
 * diagonally located, the other is straight on (as in the diagram).
 * We consider two more squares further out (marked below as ?).
 *
 * We assign "option" to the straight-on grid, and "option2" to the
 * diagonal grid, and "check_dir" to the grid marked 's'.
 *
 * ##s
 * @x?
 * #.?
 *
 * If they are both seen to be closed, then it is seen that no benefit
 * is gained from moving straight. It is a known corner.  To cut the
 * corner, go diagonally, otherwise go straight, but pretend you
 * stepped diagonally into that next location for a full view next
 * time. Conversely, if one of the ? squares is not seen to be closed,
 * then there is a potential choice. We check to see whether it is a
 * potential corner or an intersection/room entrance.  If the square
 * two spaces straight ahead, and the space marked with 's' are both
 * unknown space, then it is a potential corner and enter if
 * find_examine is set, otherwise must stop because it is not a
 * corner. (find_examine option is removed and always is TRUE.)
