Source URL and Links needs to be rendered as Hyperlinks

The Source URL and Links inside the exported PDF needs to be rendered as Hyperlinks to be correctly usefull, verifying the code print.pages.inc was found that this was returning the tag P not an hyperlink: "<p><strong>" . t('Links') . "</strong><br />$url_list</p>"; The main problem is if we try to generate a pdf and the path is too long the line will break and the path will be cutted invalidating the same. Another point found is that for the adobe and other tools that render pdf files if the path isn't a hyperlink this will not be clickable, i have attached the code with some modification into the print.pages.inc file, if you guys could please review it i will appreciatte,

/**

function theme_print_sourceurl($vars) {
  $sourceurl_date = variable_get('print_sourceurl_date', PRINT_SOURCEURL_DATE_DEFAULT);

    $output .= ')';
  }
  $new_url = explode("base_url", $url);
  $output .= ':</strong>' ."<a href=".$new_url[1].">". $url . '</a>';

  return $output;

  // Display the collected links at the bottom of the page. Code once taken from Kjartan Mannes' project.module
