The point of my comment was that with Andy's definition of when

that have the same contents at that path.  External tools can do
stupid things and that is what you are calling the rope.  But
the case I am talking about is that we deliberately do _not_
call external tools, so even if external tools can do sensible
things if given a chance to, they are not given a chance to do
so, and deciding not to call them in some cases is made by us.

And that's a fairly acceptable limitation IMHO, which doesn't make the 
thing any less useful for many cases.  We just need to document it 
appropriately.
