507     * player hiding along a corridor at right angles to the corridor with the monster.
508     *
509     * Modified by MSW 2001-08-06 to handle tiled maps. Various notes:
510     * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
511     * down corriders.
512     * 2) I think the old code was broken if the first direction the monster
513     * should move was blocked - the code would store the first direction without
514     * verifying that the player can actually move in that direction. The new
515     * code does not store anything in firstdir until we have verified that the
516     * monster can in fact move one space in that direction.
517     * 3) I'm not sure how good this code will be for moving multipart monsters,
518     * since only simple checks to blocked are being called, which could mean the monster
519     * is blocking itself.
