Caching cuts down String#scan calls by ~30% and produces no
perceivable difference in scrolling responsivenes.

After String#display_length caching the main cpu hog is
Ncurses::WINDOW#method_missing, which dispatches calls to wide char or
ordinary Ncurses methods depending what's available.  Gonna try to
hardwire Ncurses::WINDOW#mvaddstr next.

Now that I really look into this.  The performance I see (sup runnin
screened on Bytemark VPS) is considerably better that what is seen on
the video.  It is definitely not fast, but otoh I can't make it lag
behind like it does on the video.
