title: List all files changed by a specific user in a Git repository
body: <p>How do I get a list of all files changed by a specific user in a Git repository?</p>
  
  <p>Using <code>$ git blame</code> will tell you who has changed each line of a file, but that's only limited to one file, includes the whole line by default, and doesn't include historic changes that might have been overwritten.</p>
  
  <p>I  would like some command (or short script) that will produce a list of all files changed by a specific user.</p>
