[[[
Fixed problem in svnlook.py where diffing a versioned file produced an
'list index out of range' error in DiffEditor.apply_textdelta().

* tools/examples/svnlook.py
  (DiffEditor.apply_textdelta): Removed third argument in _do_diff() call
    since it was unnecessary and referenced an invalid list index.
