title: Git pull requests only certain commits on bitbucket
body: <p>What happens if you only want to pull request some commits but not all?</p>
  
  <p>say you have a repo, Foo, and forked that repo as Bar. you then make commits 1 and 2 to Bar. I only want to pull commit 2 back to Foo, how can I do that? </p>
  
  <p>I'm using bitbucket as git host so i'm pretty sure i need to do it on command line. Thx.</p>
