[Done v1.6.0] Redundant code in init_sanitize.php

[i-make-robots]

/**
 * process all $_SESSION terms
 */
  if (isset($_SESSION) && count($_SESSION) > 0) {
    foreach($_SESSION as $key=>$value){
      if(is_array($value)){
        foreach($value as $key2 => $val2){
          unset($GLOBALS[$key]);  // <<-- shouldn't this be key2 ?
        }
      } else {
        unset($GLOBALS[$key]);
      }
    }
  }

It's actually redundant.

The redundant code will be removed in v1.6.0.

Leaving it as-is is harmless. THERE IS NO NEED TO APPLY THIS TO EXISTING SITES PRIOR TO UPGRADING TO 1.6.0

THIS IS NOT A BUG. Merely inefficient code, probably leftover from some legacy components.
