Checkout Github Pull Requests locally without adding remotes

config

# Edit the .git/config file in your local repo like so:
#   cd <path/to/project>
#   vim .git/config
# (include the lines below)

[remote "origin"]
    url = https://github.com/bryanbraun/anchorjs.git
    fetch = +refs/heads/*:refs/remotes/origin/*
    fetch = +refs/pull/*/head:refs/pull/origin/*

# Note: The last line is the new one. The other lines will already be present
#       if you have defined a remote repository named "origin".

# Now to checkout a pull request locally (like PR #14), just run:
#  git fetch origin
#  git checkout -b branch-name refs/pull/origin/14
