Ticket #2453: aggressive screen repaint 

... to avoid artefacts after printing of non-printable symbols.

(tty_touch_lines): new function to mark modified lines of screen.
(do_refresh): mark lines as modified before redraw of non-fullscreen dialog
and clear entire screen before redraw of fullscreen dialog.
