Git: pull out a specific branch, save only the last tree (without any history)

Question

How can I pull a specific branch from a remote repository, checking only the last tree without saving history?

This question is specifically related to checking the Gentoo Portage tree: I would like to update my Portage tree without saving any history, minimizing size /usr/portage/.git.
