Updated bzr vs hg vs git benchmarking results

[Ian Clatworthy]

Bazaar 2.0 now looks pretty hot vs Mercurial 1.3 w.r.t storage
efficiency. I'm still collecting some results for bzr vs git. See
http://bazaar-vcs.org/Benchmarks.

If benchmarking is your thing, please let us know how 2.0 stacks up for
your project by blogging and linking to your post from that page. In
particular, it would be great if:

* we had updated performance data, speeds not just sizes.

* someone added a Bazaar 2.0.0 vs Subversion 1.6 section to that page.
