bug#6665: 24.0.50; rgrep does not work on Windows

User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (windows-nt)

rgrep does not work on Windows. I am using the GnuWin32 versions of
find and grep and find returns an error when used by Emacs' rgrep.

Start Emacs with `emacs -Q'. 

In *scratch* buffer evaluate the following to point to GNU find and grep 
(setq find-program "\"C:/Program Files (x86)/GnuWin32/bin/find.exe\"")
(setq grep-program "\"C:/Program Files (x86)/GnuWin32/bin/grep.exe\"")

Run `M-x rgrep'. Search for "emacs" in files "all" in base dir
"d:/devel/emacs/emacs-bzr/trunk/src/oo-spd/i386/" (or something similar).

*grep* buffer output:
-*- mode: grep; default-directory: 
"d:/devel/emacs/emacs-bzr/trunk/src/oo-spd/i386/" -*-

`M-x grep' and `M-x lgrep', as well as `M-x grep-find' work fine.

http://linux.die.net/man/1/find talks about this particular error in section
"Non-bugs", but as far as I can tell the files are enclosed in quotes correctly.
