Subversion stores files as fully expanded versions, and as deltas
between the versions. It has a fancy algorithm internally so the maximum
number of deltas it needs to apply to get to a particular version
increases logarithmically with the number of versions stored. Basically,
retrieving an old version is pretty cheap.
