Add some braces to a loop in parse_opts(). A for loop had no braces around its body, which was a single if-else statement. In Advanced Rogue 5, another statement had been added, accidentally removing the if-else from the loop. This could have resulted in an out-of-bounds access to the options array. In the other games, the added braces are only for clarity.
