This isn't the first time I've heard concerns about using hashes for checking file equality. I've considered adding a "paranoid mode" to do the direct byte-for-byte checks for such folks that don't even want to introduce a so-remote-it's-virtually-impossible theoretical chance for a collision to occur.
I'd go into the math about how remote of a chance it would be (barring any discovered hash collisions) but others have explained it better than me elsewhere.
