Compression means that the entire file changes every time there is a change to 
a part of it.  So the repository cannot efficiently store just the differences.

So every time there is a change to the documentation, the repository size goes 
up by the size of the file.  Since everybody checks out the whole repository, 
this affects everybody's disk space.  I imagine that compression gives us about 
50% only.  Roland, how much does compression save?
