8c912ee (teach --histogram to diff, 2011-07-12) claimed histogram diff was faster than both Myers and patience. We have since incorporated a performance testing framework, so add a test that compares the various diff tasks performed in a real 'log -p' workload. This does indeed show that histogram diff slightly beats Myers, while patience is much slower than the others.
