Summary: value of a variable can't be '0'

Initial Comment:
 I got a template variable FILE_NB which can be equal to the string 0 
.  
But template function evaluate 0 as null and so gives me an error:  
<b>Template Error:</b> loadfile: FILE_NB is not a valid handle.<br>  
  
Test with this script to see the problem:  
  
require 'template.inc';  
  
$t = new template('/tmp');  
//no matter what page.tpl contains   
$t->set_file('page','page.tpl');  
$t->set_var('FILE_NB','0');  
$t->parse('out',array('FILE_NB','page'));  
  
  
Suggested modification:  
  
on the first line of the loadfile function, replace the test:  
!empty($this->varvals[$handle])  
with  
strlen($this->varvals[$handle])
