title: Is there a way to get the amount of lines changed in a Pull Request via the Dev Ops Service REST API?
body: <p>I am currently doing my thesis and analyzing the behavior for code reviews. For this I want to know the size of the pull request that is reviewed. The rest of the information for example authors, reviewers, times etc. I got already by calling the rest API. However I cannot seem to find a way to get the amount of lines changed in each file, or a total number (which is also sufficient).</p>
  
  <p>I have browsed the documentation and found some ways to get amount of files changed, see <a href="https://docs.microsoft.com/en-us/rest/api/azure/devops/git/commits/get%20commits?view=azure-devops-rest-5.1" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/rest/api/azure/devops/git/commits/get%20commits?view=azure-devops-rest-5.1</a>. However, I didn't found a way to get the amount of changed lines per file or a total amount.</p>
  
  <p>So is there a way to get amount of lines changed in a Pull Request or between two commits?</p>
