Signup confirmation mail subject not translatable

  $params = array(
    'subject' => token_replace('Signup confirmation for [node:content-type]: [node:title]', array('node' => $node, 'signup' => $signup)),
    'body' => token_replace($node->signup_confirmation_email, array('node' => $node, 'signup' => $signup, 'global' => NULL)),
    'node' => $node,
    'signup' => $signup,
  );

Shouldnt it look like the following:

  $params = array(
    'subject' => token_replace(t('Signup confirmation for [node:content-type]: [node:title]'), array('node' => $node, 'signup' => $signup)),
    'body' => token_replace($node->signup_confirmation_email, array('node' => $node, 'signup' => $signup, 'global' => NULL)),
    'node' => $node,
    'signup' => $signup,
  );
