title: TortoiseGit change default port 22
body: <p>It's probably an easy question.
  I'm running on windows 8, and I want to connect to my company's repository. My company changed the default port from 22 to 1234 for some administrative reason.</p>
  
  <p>My git repository looks like git@office.comp.com:proj.git .</p>
  
  <p>First of all I don't understand the colon-notation in ':proj.git', I'm used to the slash-notation.
  Secondly I want a way to pull and push on that port either using TortoiseGit or from the command line.
  I tried changing the url like git@office.comp.com:1234:proj.git and git@office.comp.com:proj.git:1234, but no hope.</p>
  
  <p>I always get a connection timeout error.
  I used the <code>ssh -vT -p 1234 git@office.comp.com</code> in the command line and it was able to connect. </p>
  
  <p>So now I'm confused, I was able to connect using the ssh command but I don't know how to use it inside TortoiseGit.</p>
