- * <pre>
- * 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.

- * \#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.)
