title: Prune all git remotes
body: <p>Does Git have anything akin to <code>git remote prune --all</code> to automatically prune all remotes in a repository? Is there anything more built-in (or elegant) than this bash loop I've used?</p>
  
  <pre><code>for REMOTE in `git remote`; do git remote prune $REMOTE; done
  </code></pre>
