How I git clone rails 1-2-stable ?

RoR People,

I looked at this URL:
  http://dev.rubyonrails.org/

I see that I can do this:
  git clone git://github.com/rails/rails.git

I tried it and it gave me RoR 2.1.

How do I git clone rails 1-2-stable ?
What is the URL?

RoR People,

I tried this:
  git clone git://github.com/rails/rails.git
  cd rails
  git branch -r (to see a list of releases)
  I saw:
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$ git branch -r
      origin/1-2-stable
      origin/2-0-stable
      origin/2-1-stable
      origin/HEAD
      origin/master
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$
  I did:
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$
    mac2:/pt/w/mmhq/git_of_RoR/rails maco$ git checkout
origin/1-2-stable
    Note: moving to "origin/1-2-stable" which isn't a local branch
    If you want to create a new branch from this checkout, you may do so
    (now or later) by using -b with the checkout command again. Example:
      git checkout -b <new_branch_name>
    HEAD is now at 5b3f756... Remove wasteful signal trap from
transactions. Backport from 2-0-stable.

*SVN*

* Fix :cookie_only to correctly avoid session fixation attacks
(CVE-2007-6077)

* Fix regression where the association would not construct new finder
SQL on save causing bogus queries for "WHERE owner_id = NULL" even after
owner was saved.

I now have a copy of 1-2-stable (1.2.6 actually) and I am happy!
