title: Remove a file from the pull request
body: <p>I have made all my changes on a branch created form master and then raised a pull request on the repository and got a review comment form my team mate about reverting a file.</p>
  
  <p>Which is not actually changed by me, seems like my editor atom settings has added a new line at the end but for some reason i try to revert it twice. I get the same issue either by deleting one line extra or adding a space not sure how to resolve this issue.</p>
