Did I miss something? git-clone doesn't grab all branches????

I used to be able to do this:

git-clone http://ftp.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git cd powerpc git-checkout for-2.6.22

But that doesn't work any more.  Why not?  It was working perfectly fine before.

So someone told me I need to do this:

git-clone http://ftp.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git cd powerpc git-fetch http://www.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git for-2.6.22:for-2.6.22 git-checkout for-2.6.22

Ok, fine, but now when I do git-pull, I get this:

[snip]
* refs/remotes/origin/merge: fast forward to branch 'merge' of 
http://ftp.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc
   old..new: e0f2e3a..190a440
Warning: No merge candidate found because value of config option
          "branch.for-2.6.22.merge" does not match any remote branch fetched.
No changes.

What does the warning mean?  And why is it so difficult to clone branches now?
