title: Hg Merge specific commit from another branch
body: <p>I have two branches Dev and Feature1. I was working on Feature1, creating said feature, and committed it. I then wrote the code for Feature2 but committed it under Feature1 branch instead of a new branch (Feature2). So now i have two features in Feature1 branch as two separate commits, but I only want to include the second feature back into Dev.</p>
  
  <p>What is the mercurial way to do this?</p>
