[23.1.50] C-y not processed immediately on a terminal

[Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp>]

For several months I felt annoying that Emacs on a terminal (emacs
-nw) ignored "C-y" until next key input. Even C-q C-y is not processed
immediately ("^Y" doesn't show up on the screen) until I type another
key. I tried from C-a to C-z, and only C-y was affected. It occured
with emacs -Q -nw.

Today I learned how to use "git bisect", did bisecting, and found the
bad commit.

Before this commit, C-y worked just fine. Handa-san, could you please
review the code and fix the problem? I'm sorry I don't understand the
code at all, so I can't fix it by myself...

I'm running Emacs 23.1.50 on FreeBSD 8.0R (x86_64).
