Ah neat! Thanks for the link.  Now to wire that up to fugitive:
http://vimcasts.org/episodes/fugitive-vim-exploring-the-history-of-a-git-repository/

The LLVM project recently switched to git from svn.  For quite some
time the move was delayed in order to preserve history (including for
parked release branches and all kinds of edge cases and things that
don't quite translate from svn to git).  Now I better appreciate the
history preservation.
