patch 8.1.0856: when scrolling a window the cursorline is not always updated
Problem: When scrolling a window other than the current one the cursorline
highlighting is not always updated. (Jason Franklin)
Solution: Call redraw_for_cursorline() after scrolling. Only set
w_last_cursorline when drawing the cursor line. Reset the lines
to be redrawn also when redrawing the whole window.
