title: Git .netrc file authentication issue
body: <p>I am using GitHub. I created a repository and cloned it on my Ubuntu machine.
  I have made an entry in the <code>.netrc</code> file as follows:  </p>
  
  <pre><code>machine https://github.com/xxx/yyy.git
  login xxx
  xxx
  </code></pre>
  
  <p>I am expecting that Git will not ask me for the username and password after this entry in the <code>.netrc</code> file. But Git prompts for credentials even after this.  </p>
  
  <p>Am I missing something?</p>
