Patch 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>.
