Hi emacsers

I am wondering how to show the count of matches when grep-find. Like the
following.
,-----------
| -*- mode: grep; default-directory:
"d:/ntemacs23/myemacs/private_data/out_of_svn/" -*-
| Grep started at Mon Jun 28 17:46:18
|
|  find . -name ".svn" -prune -o -type f -print0 | xargs -0 -e grep -inH -e
emacs
| ./#tmp.txt#:7:#+TAGS: ARCHIVE(a) WEBPAGE(w) LIFE(l) EMACS(e) IMPORTANT(i)
HARD(h) COMPUTER(c) RECOMMENDATE(r) Tool(t)
| ./#tmp.txt#:47438:* TODO log4j-mode in emacs
| ./#tmp.txt#:47529:Hi emacsers
| ./tmp.html:554:<p class="creator">HTML generated by org-mode 6.35i in
emacs 23</p>
| ./tmp.html~:153:<p class="creator">HTML generated by org-mode 6.35i in
emacs 23</p>
| ./tmp.txt:7:#+TAGS: ARCHIVE(a) WEBPAGE(w) LIFE(l) EMACS(e) IMPORTANT(i)

`-----------

IMHO, one feasible way may be counting the output of *grep* buffer.
Before moving any further, I am very willing to hear your ideas, comment or
codesnipet for this?
