title: how to find files in a given branch
body: <p>I noticed that when doing code view, people here in my company usually just give the branch in which his work is done, and nothing else. So I guess there must be a easy way to find out all the files that has a version in the given branch which is the same thing to find all the files
  that has been changed. </p>
  
  <p>Yes, I don't know the expected "easy way" to find files in certain branch, so need your help and thanks in advance.</p>
