title: Github API - commits by author
body: <p>I am wondering if it is at all possible to use GitHub's API<sup>1</sup> to retrieve a list of commits by a given author (for a specific repository, branch).  One can grab recent commits to a repository and branch (e.g. mojombo's grit repository's master branch in JSON format: <a href="http://github.com/api/v2/json/commits/list/mojombo/grit/master" rel="noreferrer">http://github.com/api/v2/json/commits/list/mojombo/grit/master</a>) but I would like to know if it is possible to filter this by author (hopefully it is just something I've missed in the documentation or is available but not documented).</p>
  
  <p>So, does anyone know if something exists like <a href="http://github.com/api/v2/" rel="noreferrer">http://github.com/api/v2/</a><code>:format</code>/commits/list/mojombo/grit/master/<code>:authorname</code> (this obviously does not work). I am also open to suggestions about generating such a list myself (via the <code>git</code> command). Any ideas? </p>
