This turned to be somewhat more involved than I originally expected. Given the relative pack reduction resulting from that, I might have decided against doing this if I had known beforehand how much work was needed. But since it is done now I think it is worth merging nevertheless. Some parts are still pure code cleanups anyway. Overall the larger projects are likely to benefit more as they have a larger proportion of deltas. On the historic Linux archive the pack reduction is about 5%. Nicolas
