    Print which option was in error along with usage message
    
    Special case -u, since it's documented as printing the usage message
    (sort of like an ancient --help), so shouldn't be called unrecognized.

    Actually print command list in usage message
    
    The xauth routine this was based on took three arguments:
    a file pointer, a command name, and a prefix.
    
    If a command name is given, prints help on that command,
    else if it's null, prints help on all commands.
    
    The iceauth version has only two arguments: file pointer & command name.
    It was being called with file pointer & prefix, and since the prefix
    matched no command names, no help was printed.
    
    Since the way iceauth's help list is structured doesn't make it easy
    to add a prefix to every line, skip indentation for now and just pass
    NULL for the command argument.
