I think Dirk's explanation is reasonable. It seems to me that excessive
UNUSED_PARAM masses up codes. From a code readability perspective it is
good to use them commented out when parameter type or function name don't
stand for nothing. If Dirk's suggestion is best, IMHO, it would be good if
someone adds this(/* */) to #9 of webkit coding style Names as well.
