First let me say that this is a very nasty thing to do.  People are using
google to search for a particular thing, and they found it on a particular
portion of your site.  But you are preventing them from accessing that and
shoving them back to your homepage.  This blows the whole purpose of
search engines.  Google is very aggressive in finding and punishing this
kind of manipulation, so if you do this, you may find your site removed
from google entirely.  Even if they don't, I would be loath to visit a
site that did this to me.

Having said that, the proper technique is

RewriteEngine On
RewriteCond %{HTTP_REFERER} ^http://www\.google\.com/  [NC]
RewriteRule /.+ [R,L]

Your rule said "match any URL with zero or more slashes" (which makes no
sense even if it did not create a loop).  My rule says "match any URL with
a slash followed by at least one more character".  So my URL will not
rewrite if the user hits the site homepage, thus preventing the loop you
