title: GitHub pull request template: get current branch name
body: <p>I'm creating a pull request template for my repository.</p>
  
  <p>I added a new file, following the instructions at <a href="https://help.github.com/articles/creating-a-pull-request-template-for-your-repository/" rel="noreferrer">https://help.github.com/articles/creating-a-pull-request-template-for-your-repository/</a> , and now I want its' body to contain a string generated using the current branch name (the pull request branch name).</p>
  
  <p>Couldn't find the answer in GitHub's docs, would like to know if it's possible and if so how?</p>
