title: TortoiseGit... pull remote branch into different local branch
body: <p>I'm working on a local branch and want to merge the latest remote master into this to get it up to date with other changes merged to master from a different branch.</p>
  
  <p>I'm new to git, but TortoiseGit is making it more confusing as it doesn't seem to use exactly the right terminology in the exact same way.</p>
  
  <p>Can I even do this, or do I have to update my entire local repo and then merge my local master -> local branch?</p>
