    Fix indentation/if brace error
    
    As beep.c is not Python, the code blocks must be defined by
    using braces instead of just indenting them differently.
    
    Once we do that, the outcome of multiple -f parameters will
    actually match what the warning message documents beep does:
    Only the last -f value will be used.
    
    Many projects proscribe using braces everywhere, but this
    change keeps the beep.c coding style of using braces only
    when absolutely necessary.
    
    This issue was discovered by compiling with gcc 6.
