Btw, I guess you already know it, but if you need to clone the git
repository (for example David's) and then you would like to update it
using git-svn with the latest svn from scipy, here is the howto:

E.g. basically:

git svn init http://macromates.com/svn/Bundles/trunk/Bundles/Ruby.tmbundle
-R svn
cp .git/refs/remotes/origin/master .git/refs/remotes/git-svn
git svn fetch
