Summary: backslashes lost by subst()

Initial Comment:
The subst() function in template.inc uses 
preg_replace to merge variables with page 
content. The trouble with preg_replace is that its 
second argument, the replacement string, is 
treated in a "grep-like" way, such that the 
backslash character has a special meaning. So 
every backslash needs to be doubled before doing 
the replacement, or else every other one will be 
stripped out.

To fix the preg_replace problem I changed the 
subst() function like so:

 function subst($handle) {
   if (!$this->loadfile($handle)) {
     $this->halt("subst: unable to load $handle.");
     return false;
   }
 
   $str = $this->get_var($handle);
 
   // THESE LINES WERE ADDED BY ME
   foreach ($this->varvals as $k=>$v)
       $this->varvalsfixed[$k] = preg_replace('/\/', '\\', 
$v);
 
   // AND I CHANGED THIS LINE TOO
   $str = @preg_replace($this->varkeys, $this->
varvalsfixed, $str);
 
   return $str;
 }
