The old code used getstarg() to get an argument with a different prompt than snxtitem() uses, then passed the value to snxtitem() unchecked. If the player aborts, getstarg() returns a null pointer, and snxtitem() prompts again. Affected: * load/lload plane/land third argument; load_plane_ship(), load_land_ship(), load_plane_land(), load_land_land() * bomb, drop, fly, paradrop, recon and sweep second argument; get_planes() * tend and ltend second and fourth argument; ltend(), tend(), tend_land() * mission second argument; mission() Fix by making snxtitem() taking a prompt argument, null pointer requests the old prompt. Use that to simplify multifire() and torp(). Change the other callers to pass NULL.
