Date: Fri, 18 Nov 2011 22:36:55 -0800

This seems to be a bug. Steps to reproduce:

• Start GNU Emacs with -Q.

• call “rgrep”. Search for anything.

• You get the following result:

GNU Emacs 23.2.1 (i386-mingw-nt6.1.7601) of 2010-05-08 on G41R2F1
Windowing system distributor `Microsoft Corp.', version 6.1.7601
configured using `configure --with-gcc (3.4) --no-opt --cflags -Ic:/xpm/include'

I'm also running Cygwin for the unix util grep.

It appears, that the problem is because emacs is calling cmd.exe's
grep, not cygwin. Perhaps `grep-compute-defaults' should know about
it.
