Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

"""Kenneth Reitz's GitHub Syncer
This script uses the GitHub API to get a list of all forked, mirrored, public, and
private repos in your GitHub account. If the repo already exists locally, it will
update it via git-pull. Otherwise, it will properly clone the repo.
It will organize your repos into the following directory structure:
