title: How do I disable git's credential helper for a single repository?
body: <p>If I have a credential helper set in my <code>~/.gitconfig</code>, how can I disable/bypass it in a specific repo and use <em>no</em> credential helper?</p>
  
  <p>I've tried editing the repo's <code>.git/config</code> file to blank out the <code>credential.helper</code> property like this:</p>
  
  <pre><code>[credential]
      helper = 
  </code></pre>
  
  <p>... but when I do a <code>git push</code> I get the following error message, and Git uses my default credential helper from <code>~/.gitconfig</code> anyway:</p>
  
  <pre><code>git: 'credential-' is not a git command. See 'git --help'.
  
  Did you mean this?
          credential
  </code></pre>
  
  <p>I'm using git version 1.7.12.</p>
  
  <p>(Backstory/use case: Git is configured to use the <code>store</code> helper, which stores passwords unencrypted on disk. The <code>cache</code> helper is unavailable on this system. I have a couple repos for which I'd rather type the password every time than keep it on disk.)</p>
