title: Git log without an author's commits
body: <p>There's a project we're working on where the majority of commits are added in by a front-end developer.  He's editing mainly HTML, CSS, JavaScript files that are not related to the back-end work that I'm helping with.  It would be great if I could show the <code>git log</code> minus commits added by the front-end developer, so I could get a view of commits just related to the backend. </p>
  
  <p>Is there an option I can pass to <code>git log</code> that would allow me to <strong><em>exclude</em></strong> all commits by an author? I just want to exclude this one developer's commits, <strong><em>I still care about viewing commits from other developers</em></strong> as well.</p>
