Actually it looks like your entire commit history has been preserved in git, at least starting from 1997:

  $ git log --pretty=oneline | wc -l
      4753

  $ git log ada086d0cec0be47811b3d686017e84e041a5201
  commit ada086d0cec0be47811b3d686017e84e041a5201
  Author: Repo Admin <nobody@gnupg.org>
  Date:   Tue Nov 18 14:06:00 1997 +0000

    New repository initialized by cvs2svn.

The stats from my comment above were just from the parents git log start..end timeframe though.

Here looks to be the stat report from the entire history: https://gist.github.com/anonymous/352d28b459d0fc286dab
