 * important as the language of the node we're linking to, and even then only
 * if language path prefixing (eg /ja/node/123) is in use. REMEMBER THIS IN THE
 * FUTURE, ALBRIGHT.
 *
 * The below code uses the @ operator before parse_url() calls because in PHP
 * 5.3.2 and earlier, parse_url() causes a warning of parsing fails. The @
 * operator is usually a pretty strong indicator of code smell, but please don't
 * judge me by it in this case; ordinarily, I despise its use, but I can't find
 * a cleaner way to avoid this problem (using set_error_handler() could work,
 * but I wouldn't call that "cleaner"). Fortunately, Drupal 8 will require at
 * least PHP 5.3.5, so this mess doesn't have to spread into the D8 branch of
 * Pathologic.
