2048 * The monster is known to be within 100 grids of the player\n
2050 * In several cases, we directly update the monster lore\n
2052 * Note that a monster is only allowed to "reproduce" if there\n
2053 * are a limited number of "reproducing" monsters on the current\n
2054 * level. This should prevent the level from being "swamped" by\n
2055 * reproducing monsters. It also allows a large mass of mice to\n
2056 * prevent a louse from multiplying, but this is a small price to\n
2057 * pay for a simple multiplication method.\n
2059 * XXX Monster fear is slightly odd, in particular, monsters will\n
2060 * fixate on opening a door even if they cannot open it. Actually,\n
2061 * the same thing happens to normal monsters when they hit a door\n
2063 * In addition, monsters which *cannot* open or bash\n
2064 * down a door will still stand there trying to open it...\n
2066 * XXX Technically, need to check for monster in the way\n
2067 * combined with that monster being in a wall (or door?)\n
2069 * A "direction" of "5" means "pick a random direction".\n

3278 * monster, and allowing fully energized monsters to move, attack, pass, etc.\n
3280 * Note that monsters can never move in the monster array (except when the\n
3281 * "compact_monsters()" function is called by "dungeon()" or "save_player()").\n
3283 * This function is responsible for at least half of the processor time\n
3284 * on a normal system with a "normal" amount of monsters and a player doing\n
3287 * When the player is resting, virtually 90% of the processor time is spent\n
3288 * in this function, and its children, "process_monster()" and "make_move()".\n
3290 * Most of the rest of the time is spent in "update_view()" and "lite_spot()",\n
3291 * especially when the player is running.\n
3293 * Note the special "MFLAG_BORN" flag, which allows us to ignore "fresh"\n
3294 * monsters while they are still being "born". A monster is "fresh" only\n
3295 * during the turn in which it is created, and we use the "hack_m_idx" to\n
3296 * determine if the monster is yet to be processed during the current turn.\n
3298 * Note the special "MFLAG_NICE" flag, which allows the player to get one\n
3299 * move before any "nasty" monsters get to use their spell attacks.\n
3301 * Note that when the "knowledge" about the currently tracked monster\n
3302 * changes (flags, attacks, spells), we induce a redraw of the monster\n
