Insert n blank lines at the cursor

<p>
Lines at the bottom of the viewport are removed and all the lines between the cursor and the
bottom of the viewport are shifted down, to make room for n blank lines. None of the lines
above the cursor are affected, including those in the scroll-back buffer.

@param n the number of lines to insert
