If you add

  (message "%s" (point))

to the form inside with-selected-window, you will see that
forward-line does its job perfectly.  Also, the line number in the
mode line gets incremented, even if you don't make the above addition.
The problem is that the window showing the *Completions* buffer is not
scrolled to bring point into view.
