Incremental diffs for the Index files. One per day. But you get 3
messages for each for downloading, gunzip and rred respectively. 3
times as much for main/contrib/non-free, double if you have etch and
sid, double again for source.

That can be a lot of pdiff files even for just one day. But they are
tiny, they just take way too much cpu time to process currently.
