Hello,

There is just one git URL for all the branches: 
https://github.com/qgis/QGIS.git

but you can change to a different branch using the -b command switch 
(e.g: git checkout -b threading-globe origin/threading-globe).

You can use this page to get more info on git:

http://hub.qgis.org/projects/quantum-gis/wiki/Using_Git

or you can Google for it.
