Kalle Olavi Niemitalo ff4c103a78 Bug 827, display_codepage: Call option_changed. 
This change allows screen_driver_change_hook to detect that the
charset has been changed to UTF-8 and set screen_driver.utf8 = 1.
redraw_screen then calls get_screen_driver, which propagates the flag
to terminal.utf8.  That in turn avoids an assertion failure in
handle_interlink_event.
