Some time ago, the brilliant GitHub people gave me the following tip. Rajarshi is lazy, and might find it interesting. By appending .patch to the commit URL, a commit can easily be downloaded as patch. For example, Dmitry made this commit in his branch, having the URL https://github.com/dmak/cdk/commit/9b0478d50c7b5ca10f77fb01d89329db5fe80625. The patch for this commit can then be downloaded at this URL https://github.com/dmak/cdk/commit/9b0478d50c7b5ca10f77fb01d89329db5fe80625.patch.
That way, developers can easily download it with wget and apply it locally with git am, without having the fetch the full repository.
