Question about git

[Michel Boaventura]

Hello guys,

When I type  git clone git://git.savannah.gnu.org/pspp.git on my
console, git downloads the last version of master branch to my pc.
How do I tell it to download the last stable branch? Is there a way to
have on the same folder both branches, and change betwen they
easily?

Thanks,

Michel Boaventura
