title: What are you supposed to do with old SVN branches?
body: <p>We had a SVN branch recently that had been merged back to trunk, and some more work on that feature/functional area was needed. I suggested using the same branch but was told you shouldn't re-use a branch once it has been integrated into trunk (a reference in SVN docs was given, I can't find it now).
  That suggests a branch is fairly useless once you merge back to trunk, so my question is once a branch is no longer needed, should it simply be deleted or kept?</p>
