arguments in views titles forced into uppercase

As discussed in: http://drupal.org/node/242501

In views_node.inc<code> for both the views 1.6 release and the May 10 '08 dev build, there is code forcing the the arguments in views titles into uppercase (last two lines of the function below, around line 538). It seems undesirable to me to force capitalization because users lose exact control over case in their node titles. Removing the <code>strtoupper() from $query gets rid of the uppercase.

function views_handler_arg_nodeletter($op, &$query, $argtype, $arg = '') {
  static $field = NULL;
  switch($op) {
    case 'summary':
      $len = intval($arg);
      $field = $fieldinfo['field'] = ($len <= 0 ? "node.title" : $fieldinfo['field'] = "LEFT(node.title, $len)");
      $fieldinfo['fieldname'] = 'letter';
      return $fieldinfo;
      break;
    case 'sort':
      $query->add_orderby('node', $field, $argtype, 'letter');
      break;
    case 'filter':
      $len = intval($argtype['options']);
      if ($len <= 0) {
        $query->add_where("node.title = '%s'", $arg);
      } else {
        $query->add_where("LEFT(node.title, $len) = '%s'", $arg);
      }
      break;
    case 'link':
      return l(strtoupper($query->letter), "$arg/$query->letter");
    case 'title':
      return check_plain(strtoupper($query));
  }
}

The capitalization does not seem to happen with the 1.5 release of Views, even though the function views_handler_arg_nodeletter() looks pretty much the same (with strtoupper()).

Is it feasible to remove strtoupper()</copde> from <code>$query so that titles with arguments have flexible case again? Or is there another option? Did the handling of argument title formatting change somehow between the two versions?

Thanks for any assistance.
