title: vagrant ssh can't find the ssh executable
body: <p>I have the usual vagrant ssh problem with usual suggestion:</p>
  
  <pre><code>Try installing Cygwin, MinGW or Git, all of which
  contain an SSH client
  </code></pre>
  
  <p>I have do this but I still have this problem. The only working solution that I've found is:</p>
  
  <ul>
  <li>install Git client</li>
  <li>open Git shell (sh.exe under <code>Program Files/Git/bin</code>)</li>
  <li>and then vagrant ssh on my project</li>
  </ul>
  
  <p>As I said, this works but I have to switch from Windows Prompt (cmd.exe) to Git Shell (sh.exe). How can (can I?) run the <code>vagrant ssh</code> without switch the consoles in Windows?</p>
