Notes...........Deletes or inserts a line from the active window.
                Depending upon the input scroll direction, the lines above
                or below the line to delete will scroll to fill in the
                deleted line in, and a blank line will be added.  If what
                you really want to do is clear the line, you may want to
                use WclrEol() instead.
