Summary: potential problem with php code

Initial Comment:
I was wondering why I was not getting RH values with
version 2.2.2  Upon further investigation it appears
that it is not calculated unless 
taken from phpweather.php 

    if (!empty($decoded_metar['temperature']['temp_c']) &&
        !empty($decoded_metar['temperature']['dew_c'])) {


now my problem with this appears that when either temp
or dew is 0 then by php 4 definition
PHP 4	

As of PHP 4, The string value "0" is considered empty. 

and therefore rh is not calculated...should !empty be
replaced with isset
