However, whether google also treats an empty path the same as a root path is a different question. I haven't been able to find any statements from google that explicitly says one way or the other. Though, I expect that they would treat them the same, since the HTTP spec treats them the same.

And just to reiterate, whether google treats them the same or not doesn't change that a rewrite rule can't enforce it. All you can do is be consistent with the way you write your HTML links.
Here Matt says how google "probably" treats them. http://www.youtube.com/watch?v=CTrdP7lJ2HU using this search "matt cutts trailing slash or not"

But regardless if the slash is left off the browser redirects to the slash. So it would be better to force the trailing slash before the browser gets it yeah??
