Forward Instructions not displaying on forward form

In admin/settings/forward you can set "Forward Instructions" to be displayed at the top of the forward page at forward/xxx, but these are currently ignored.

This is because forward_form() does:

function forward_form() {
  ...
  $output = variable_get('forward_instructions', ...);
  ...
  $output = drupal_get_form('forward_form', $form);
  ...
  return $output;
}

So the message at the top gets overwritten.

The attached patch fixes this bug.

Mark.
