455 * 2) I think the old code was broken if the first direction the monster

457 * verifying that the player can actually move in that direction. The new
458 * code does not store anything in firstdir until we have verified that the

460 * 3) I'm not sure how good this code will be for moving multipart monsters,

462 * is blocking itself.
