patch 7.4.2025
Problem:    The cursor blinking stops or is irregular when receiving date over
            a channel and writing it in a buffer, and when updating the status
            line. (Ramel Eshed)
Solution:   Make it a bit better by flushing GUI output.  Don't redraw the
            cursor after updating the screen if the blink state is off.
