commit 1b514048b254827f1a83c05e1b2a2428bf31924e
Author: Ivan Delalande <colona_AT_ycc.fr>

    Let curses do the dirty work for flash
    
    Use the terminfo delay syntax ($<x>) in our flash capability to avoid
    hardcoding a fixed delay in redraw() when called from tsetmode() with
    DECSCNM.
    We need to turn on the npc capability so that delays are made with
    xon/xoff instead of padding characters.
