title: git: track more than one remote branches
body: <p>In our git repository we have several branches, most of which are not used daily and contain gigabytes of information.</p>
  
  <p>As such, I usually work tracking the remote branch I am using:</p>
  
  <pre><code>[core]
      repositoryformatversion = 0
      filemode = true
      bare = false
      logallrefupdates = true
  [remote "origin"]
      url = https://sever/repository.git
      fetch = +refs/heads/devel:refs/remotes/origin/devel
  </code></pre>
  
  <p>How can I add an extra branch to be fetched from remote?</p>
