title: GitHub - Find the pull request associated with a commit
body: <p>I'm trying to find a past pull request to see which comments / actions were made on a particular issue. </p>
  
  <p>I know the file and the change, so I can get to the commit that introduced it by looking at the blame view. However I can't find a way to look at the pull request that pushed that commit to the branch for the first time. </p>
  
  <p>Is there a way to do this? Or do I have to go on a trip down memory lane and manually browse through past pull requests?</p>
