  // Unfortunately, the antique jQuery shipped with Drupal 5 has a bug: the
  // expression $('<tag>something</tag>') fails is 'something' contains a
  // newline. That's because jQuery's source has:
  //
  //  // Handle HTML strings
  //  if ( typeof a  == "string" ) {
  //    var m = /^[^<]*(<.+>)[^>]*$/.exec(a);
  //    if ( m ) a = jQuery.clean( [ m[1] ] );
  //  }
  //
  // Note the "<.+>", which doesn't match newlines. In newer jQuery's that
  // expression was changed to:
  //
  //  var quickExpr = /^[^<]*(<(.|\s)+>)[^>]*$|^#(\w+)$/
  //
  // Note the \s which does match newlines.
  //
  // So we have to remove all newlines:
  $output = strtr($output, "\r\n", '  ');
  return $output;
