patch 8.0.1477: redraw flicker when moving the mouse outside of terminal window

Problem:    Redraw flicker when moving the mouse outside of terminal window.
Solution:   Instead of updating the cursor color and shape every time leaving
            and entering a terminal window, only update when different from
            the previously used cursor.
