title: Set username and email for msysgit portable
body: <p>I'm using msysgit for a school project so I can do commits and such while on the computers at school which do not have it installed.</p>
  
  <p>Now the first thing one does when they install git is set up their .gitconfig how they like. However, since I cannot rely on the %HOME% directory of the computer to have the relevant file would using --system instead of --global for the git config command work?</p>
  
  <p>The main settings of course would be user.name and user.email. Would using --system work for those and all other similar settings? Would it save it to the gitconfig of the etc directory where git is installed on my USB drive?</p>
