title: Branching and Merging to a modified checkout
body: <p>Hi have a repository checkout (SVN) which has been heavily modified by a team member. We would now like to get more than 1 member on the development to speed it up. In order to prevent any overwrites, It would be ideal if they could both work on seperate copies of this modified checkout and then merge their changes together.</p>
  
  <p>Is there a way to do this in Subversion/TortoiseSVN? If not, is it an easy of a setup in git?</p>
