I was always wondering how to issue a pull request on an issue that already existed on Github…  Now I know how. Thanks to this link: http://stackoverflow.com/questions/4528869/how-do-you-attach-a-new-pull-request-to-an-existing-issue-on-github Basically all I needed to do was:

install hub
brew install hub

issue request to existing issue (must be inside git repo)

hub pull-request URL_TO_ISSUE

Now your request is made
