title: vscode not showing git password prompt
body: <p>I have a git repo on a remote server and use ssh with password authentication to clone,pull,push. From command line everything works fine.</p>
  
  <p>However in vscode when I try to pull or push from remote repository, no password prompt is shown. Vscode seems to be waiting for something but nothing happens.
  Is this a bug, or am I doing something wrong?</p>
  
  <p>I want to use visual studio code as git client on linux.</p>
