user manual wrong about remote branches?

I got the latest git source like this:

git clone git://git.kernel.org/pub/scm/git/git.git

Then I did:

make prefix=/usr/local all doc make prefix=/usr/local install install-doc

So my current version is:

git version 1.5.3.rc0.gbaa79

Now, Documentation/user-manual.txt says I should be able to see the remote branch I cloned from when I do this in the source directory.

git branch -r

However, this command gives no output at all. What gives? Does this mean git-fetch and git-pull won't work properly to keep me up-to-date with the main repository?

Thanks,
