title: "git push all" (multiple repositories) doesn't work
body: <p><a href="https://stackoverflow.com/a/4255934/11236">This answer</a> explains how to push to multiple repos simultaneously.</p>
  
  <ol>
  <li><p>My <code>.git/config</code> contains:</p>
  
  <pre><code>[remote "all"]
      url = git@github.com:commerce-sciences/scale-master.git
      url = git@heroku.ron:scale-master.git
  </code></pre></li>
  <li><p><code>git push all</code> successfully deploys to heroku.</p></li>
  <li><p>It seems that changes are not pushed to github for some reason.</p></li>
  </ol>
  
  <blockquote>
  <pre><code>&gt; git push all
  Everything up-to-date
  Everything up-to-date
  
  &gt; git status
  # On branch master
  # Your branch is ahead of 'origin/master' by 22 commits.
  #
  nothing to commit (working directory clean)
  </code></pre>
  </blockquote>
  
  <p>What am I missing?</p>
