Hello.


As far as I tried, Emacs with macOS native input method still flicker.
I use default Japanese input method of macOS.  Flicker happens when I
press RET to input selected candidates. 

This is because insertText: in nsterm.m is called and emits a special
event '(ns-unput-working-text) and then normal input events.
read_char() function which processes these events always call redisplay() 
just after processing '(ns-unput-working-text) event.

We have to prevent redisplay after '(ns-unput-working-text) event
emited by insertText:.  To do it, I made a patch.  I don’t know this
is corrent way to prevent redisplaying.
