You give me too much credit. It only means that I didn't perform the
experiment that others did.

However, my comment still applies in this sense: if you're really
seriously concerned about data integrity, you need to look at every
part of the chain that handles the data. It may well be that the
repository has MD5 integrity. But what about the data once it leaves
there? What data integrity does it have once it lands in your working
directory?
