How to include an already documented method in jsdoc-toolkit?

Question

I have a JavaScript singleton object created with closure method:

/**
 * This is the singleton.
 *
 * @namespace window.Something.Singleton
 */
window.Something.Singleton = (function() {
  /**
   * Foo method.
   *
   * @return {String} this method always returns with <code>bar</code>
   */
  function _foo() { return "bar"; }

  /**
   * @lends window.Something.Singleton#
   */
  return {
    /**
     * @borrows window.Something-_foo
     * @function
     */
    foo: _foo
  };
}());

But the jsdoc-toolkit does not generate the inherited documentation from _foo method to the foo method what I would like to have.

If I write @see instead of @borrows it works (inserts a link to the correct method), but I don't want to copy&paste the documentation for the foo method to have a public documentation as well.
