Return a themed breadcrumb trail in Drupal Commons

This is to achieve a themed breadcrumb trail with the Acquia Drupal Common theme.

You replace the default breadcrumb function in template.php in acquia_commons theme folder in profiles/drupal_commons/theme folder:

/**
 *  theme_breadcrumb()
 */

function acquia_commons_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
    return '<div class="breadcrumb">'. implode(' > ', $breadcrumb) .'</div>';
  }
}

with this code:

/**
 * Return a themed breadcrumb trail.
 *
 * @param $breadcrumb
 *   An array containing the breadcrumb links.
 * @return a string containing the breadcrumb output.
 */
function acquia_commons_breadcrumb($breadcrumb) {
  if (!empty($breadcrumb)) {
    $breadcrumb[] = drupal_get_title();
        array_shift($breadcrumb);
       return '<div class="path"><span>'.t('You are in -> ').'</span>'. implode(' / ', $breadcrumb) .'</div>';
  }
}

Note:
Of course there are dedicated contributed modules to custom breadcrumbs in theme and also this code may have to be cleaned or make it better, I'm not a coder, though.
