bug#9557: 24.0.50; "y-or-n-p" does not clear the echo area

[Dani Moncayo]

Hi,

In my init file, I have `(fset 'yes-or-no-p 'y-or-n-p)' in order to
speed up the "yes/no" answers.  But I've just seen a minor problem
associated to it.

>From "emacs -Q":
1. Eval: (fset 'yes-or-no-p 'y-or-n-p)
2. Visit some file.
3. M-x revert-buffer <RET> y
--> (Expected) The echo area ends up empty (as happens if you omit step #1).
--> (Observed) The echo area remains with a residual text "Revert
buffer from file <your-file>? (y or n)  y".
