Using deltas is an implementation detail, after all. Git already uses two types of compression (zlib on all objects, deltas between objects in packfiles). So just saying "compressing" is actually a bit ambiguous, and I think noting that what we are _actually_ doing right now is delta compression is worthwhile. -Peff
