title: Searching for a file in all Git branches
body: <p>How do I search all Git branches of a project for a file name?</p>
  
  <p>I remember part of the filename (just the ending), so I'd like to be able to search for something like <code>*_robot.php</code> across all branches, and see which files match that. I'd preferably like to have it search history, and not just the HEADs of branches.</p>
