How to clone the latest stable branch to a dir via github?

Clone from git and change to the WordPress directory

git clone git://github.com/WordPress/WordPress.git 
cd WordPress

Then list out the branches..

git branch -r 

This gives something like...

origin/1.5-branch   
origin/2.0-branch   
...
origin/3.4-branch  
origin/HEAD -> origin/master   
origin/master

Check out the branch you want...

git checkout 3.4-branch
Branch 3.4-branch set up to track remote branch 3.4-branch from origin.
Switched to a new branch '3.4-branch'

Here's what I actually ended up doing, which is included in a Fabric fabfile I have on Github:

git clone git://github.com/WordPress/WordPress.git .
git checkout $(git describe --tags $(git rev-list --tags --max-count=1))

It clones the repo like normal, then does some shell magic to find the latest tagged version of WordPress (Which is where the stable branches live.)
