Insert n blank characters at the cursor

<p>
Any characters right the cursor on the same line are shifted right to make room and n blanks
are inserted at (and to the right) of the cursor. No wrapping occurs. Characters that would
be moved or inserted right of the display buffer are effectively deleted. The cursor is
<em>not</em> moved after this operation.

@param n the number of blanks to insert.
