Errr... sorry, I should have been more explicit. What I meant here
is the result of

$ git verify-pack -v <packfile> | \
  ~/git/contrib/stats/packinfo.pl

That's huuuuge tree. Compared to that 1.6G (or 1.4G) packfile doesn't
look large.

I wonder if proper subdivision into submodules (which should encourage
better code by the way, see TAOUP), and perhaps partial checkouts
wouldn't be better solution than lazy clone. But it is nice to have
long discussed about feature, even if at RFC stage, but with some code.
