    net/radix: Fix a subtle type cast error in rn_lexobetter()
    
    The char byte comparison should be cast to 'unsigned'; otherwise, the
    result is wrong in some special cases, e.g.,
    rn_lexobetter(<255.255.0.0>, <255.255.128.0>) was giving 'true' while
    'false' is expected.
    
    While there, add a brief function description and clean up a bit for
    readability.
