title: Push to gist returning strange error
body: <p>I cloned a gist using the Public Clone URL. I made my changes, added, and committed. However when I run, <code>git push origin master</code> I get the following error:</p>
  
  <pre><code>fatal: remote error: 
   You can't push to git://github.com/1234567.git
   Use git@github.com:1234567.git
  </code></pre>
  
  <p>yet according to <code>git remote -v</code> the origin should be at the gist.github.com subdomain</p>
  
  <pre><code>origin  git://gist.github.com/1234567.git (fetch)
  origin  git://gist.github.com/1234567.git (push)
  </code></pre>
  
  <p>Any ideas on resolving this error? Thanks!</p>
