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.
