Thank you very much, Tim. Sorry for my confusing illustration.
You have point a good way to solve my problem. Changing grep-process-setup seems don't work, so I change the function of grep-find.
One slight problem is that, since the grep command takes some time, even though we define an after-defadive, the function is executed before *grep* buffer is stable.
My workaround is to sleep for some while. No idea whether we have better solution.
(defadvice grep-find (after show-grep())
(save-excursion
(setq SLEEP_INTERVAL 2)
(set-buffer "*grep*")
(sleep-for SLEEP_INTERVAL)
(message
"%d matches found"
(- (count-lines (point-min) (point-max)) 6))
)
)
(ad-activate 'grep-find)

your current point, you could:
a) put something like:
| (save-excursion
| (set-buffer "*grep*")
| (message
| "%d matches found"
| (- (count-lines (point-min) (point-max))
| 6)))
on a hot key,
b) defadvice grep-process-setup/set grep-setup-hook so that
the above will be executed when grep finishes.
