title: Git pull from specific branch with specified URL
body: <p>I am working on a branch of git. I want to take pull on this branch specifying the URL alongwith it. 
  I have tried </p>
  
  <pre><code>git pull origin &lt;branch&gt; &lt;url&gt;
  </code></pre>
  
  <p>but it says error "fatal: Invalid refspec "</p>
  
  <p>Both commands when ran independently works fine.</p>
  
  <p>1 ) <code>git pull origin &lt;branch&gt;</code> 
    Takes pull from  successfully.</p>
  
  <p>2) <code>git pull &lt;url&gt;</code>
    Takes pull from specified URL but from master branch instead.</p>
  
  <p>I want to take pull from  specifying the URL alongwith it so that it doesn't read git's config file and takes pull from 'branch' and 'url'.</p>
