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

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

487 * 3) I'm not sure how good this code will be for moving multipart monsters,
488 * since only simple checks to blocked are being called, which could mean the monster
