I am using 7.1.3 now, and it does not work:

-*- mode: grep; default-directory: "~/Programming/emacs-lisp/" -*-
Grep started at Wed Sep 30 12:12:18

grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'rcd' .

Grep finished with no matches found at Wed Sep 30 12:12:18

while in that directory I have many many results for "rcd".

So it definitely does not work.

grep -insIH --exclude="*~" --exclude="#*" --exclude="TAGS" -e 'business' .

I don't think so it will ever work recursively, the option -r is
missing or -d recurse as in manual of grep.

And you are using . as FILE argument, but with -r option, you need no
argument at all in the directory.
