Reference [2] says I should

        $ git checkout stable/tango

but that doesn't work.  Here is a typescript of how it goes wrong:

mjs10:devstack mspreitz$ git status
On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

mjs10:devstack mspreitz$ git pull
Already up-to-date.

mjs10:devstack mspreitz$ git remote -v
origin  https://github.com/openstack-dev/devstack.git (fetch)
origin  https://github.com/openstack-dev/devstack.git (push)

mjs10:devstack mspreitz$ git checkout stable/liberty
error: pathspec 'stable/liberty' did not match any file(s) known to git.
