updated for version 7.3.1288 Problem: The first ":echo 'hello'" command output doesn't show. Mapping for <S-F3> gets triggered during startup. Solution: Add debugging code for the termresponse. When receiving the "Co" entry and when setting 'ambiwidth' redraw right away if possible. Add redraw_asap(). Don't set 'ambiwidth' if it already had the right value. Do the 'ambiwidth' check in the second row to avoid confusion with <S-F3>.
