[pacman-dev] some more delta stats

[Xavier]

I generated deltas for the last 20 updates on my system. The total
delta size is 12M, while the total package size is 73M. So the overall
ratio is pretty good imo.
Afaik, only one delta on the 20 didn't reach the 0.7 ratio : attr
The ghostscript one is unbelievable : 5,7K vs 29M !

Here are the packages, deltas and their size :
