I think it doesn't work for console windows.  There's no automatic
message when the console window size changes.  There is some code
in Cygwin's console code (fhandler_console::send_winch_maybe), but
it only works when a console event is generated.  And then it isn't
called on key events.  For testing I added the call to the key event
so that the window size change is at least advertised when the next
key is pressed.

Chris, is there any good reason NOT to call send_winch_maybe on
a key event?
