title: git-bash $PATH cannot parse windows directory with space
body: <p>I would like to use git-bash come with github client on a windows 7 (32bit) machine. Somehow, the git-bash has already learned the <code>$PATH</code> variables from windows system <code>PATH</code>. However, I found the <code>$PATH</code> in git-bash did not parse the win system PATH with space correctly. </p>
  
  <p>for example the <code>$PATH</code> outputs:</p>
  
  <blockquote>
    <p>"..../c/Program: No such file or directory"</p>
  </blockquote>
  
  <p>Is there anyway to fix it? where is the git-bash script to construct the <code>$PATH</code> for git shell?
  Thanks</p>
