2804  * You may only fire items that "match" your missile launcher.
2805  *
2806  * You must use slings + pebbles/shots, bows + arrows, xbows + bolts.
2807  *
2808  * See "calc_bonuses()" for more calculations and such.
2809  *
2810  * Note that "firing" a missile is MUCH better than "throwing" it.

2812  * Note: "unseen" monsters are very hard to hit.
2813  *
2814  * Objects are more likely to break if they "attempt" to hit a monster.

2817  *
2818  * The "extra shot" code works by decreasing the amount of energy
2819  * required to make each shot, spreading the shots out over time.
