allow filters to see raw title

[chineseleper]

In /wp-includes/formatting.php

 481  function sanitize_title($title, $fallback_title = '') {
 482      $title = strip_tags($title);
 483      $title = apply_filters('sanitize_title', $title);

should be something like

 481  function sanitize_title($raw_title, $fallback_title = '') {
 482      $title = strip_tags($raw_title);
 483      $title = apply_filters('sanitize_title', $title, $raw_title);

I need this for qTranslate, qT adds XML-Comments to seperate languages, which get removed by strip_tags. Because of that, the title get mixed up with text from different languages.
