Meh... Is there any real difference? With git, I can check out any
tree state I like ("give me the 50th parent of the current HEAD"), so
in that sense it effectively stores versions - at least, it can
retrieve or recreate versions. Does it store versions and optimize
them by recording only the difference, or record differences and
replay them to recreate a state? Two sides of the same coin.
