495 * 1) With DETOUR_AMOUNT being 2, it should still go and find players hiding
496 * down corriders.
497 * 2) I think the old code was broken if the first direction the monster
498 * should move was blocked - the code would store the first direction without
499 * verifying that the player can actually move in that direction. The new
500 * code does not store anything in firstdir until we have verified that the
501 * monster can in fact move one space in that direction.
502 * 3) I'm not sure how good this code will be for moving multipart monsters,
503 * since only simple checks to blocked are being called, which could mean the monster
504 * is blocking itself.
