title: execute git pull with username and password
body: <p>Is there way to put username and password in the command with git pull,
  to avoid password message.
  for example </p>
  
  <pre><code>git pull -u ahmeditman -p 123456  #this example to explain . 
  </code></pre>
  
  <p>It is okay to use </p>
  
  <pre><code>git pull http://ahmeditmna:123456@xxxxx.git 
  </code></pre>
  
  <p>But it will pull from Master Branch, but if i need to pull from dev Branch ? </p>
