title: tortoisegit does not pull
body: <p>I am new to Git. I installed msysgit, configured ssh and pulled a solution from GitHub (my own solution, I pushed it from a different computer). 
  The pull worked. </p>
  
  <p>Now, I installed tortoisegit to make life easier. It displays the correct items in Windows Explorer. I would expect a "pull" and push entries in the context menus, but I can't find them. Where's by mistake?</p>
