title: Skip GitHub hooks on push
body: <p>We are looking for a way to disable a GitHub webhook from the command line when pushing a rebase to prevent duplicate entries in Pivotal Tracker.</p>
  
  <p>Has anyone implemented this before?  It doesn't look like <code>git push --no-verify</code> will work as I believe the webhooks in GitHub are <code>post-receive</code>.</p>
