display: do not attempt to draw a line that is outside the viewport

When we're on the last row in the viewport, it is unwise to try and draw
the next line.

This fixes https://savannah.gnu.org/bugs/?65539.
The issue was reported by `correctmost`.

Bug existed since commit c2322f85 from three days ago.
