e511ed4 by Guy Harris (guy@xxxxxxxxxxxx):

    Better fix - just check that the upper and lower nibbles are >= 0xA.
    
    An unsigned 8-bit integer is always <= 0xFF; that was the cause of the
    warning.
    
    To see whether a byte, when represented as hex, has letters for its
    upper and lower nibbles, just check whether both nibbles are >= 0xA.
    Cast the extracted nibbles to make sure there's no sign-extension.
