bug#13223: 24.2; comint history rendered useless by messages

[Tim Daly Jr.]

I always have to comment out the line (1194 in my copy) in comint.el
that does this:

(message "History item: %d" (1+ pos))

because it makes M-r in shell mode too slow to use.  You hit M-r and
type something and it just spams the heck out of you and goes nowhere.
