title: How to count the number of changed or added lines in an SVN branch?
body: <p>I would like to add up the number of line changes in an SVN branch so I can tell how far I have gone during a project from another side and estimate the probability of conflict when I merge it with trunk.</p>
  
  <p>The way I can think of is to grab the unified diff and do some grep|wc -l hacks, but the problem is it's hard to separate different file types, for example, front-end source files (.css, .html) and back-end source files(.xml, .java)</p>
