William, git can do this. Since git uses a hash it will always regenerate the same hash from the same file.
In fact, git uses hashes all the way down the tree so you can just look at the hash code of the root of the tree to see if anything changes. Equal hash codes, even across the net, imply exact copies of the source tree. Axiom uses arch, cvs, svn, and git. I have used several other systems in the past. Now all of the primary work is in git and is export-only to the other systems (git can work with them transparently). git has fundamentally changed the way I work and the way Axiom is maintained, all for the better. I know it is a challenge to change source code systems but the gain is well worth the pain in this case. The fact that git works with legacy humans is a huge plus in minimizing the pain.
