Code review comment for lp:~jml/subunit/use-traceback-content

The most recent changes (r159) make subunit's Python tests pass with testtools 0.9.11 (the documented minimum version) and with testtools trunk. Actually, it doesn't quite make them work with 0.9.11 because the TracebackContent fix in __init__.py requires 0.9.12 minimum to work.

Let me know if you want me to make that work in 0.9.11 and with trunk. Personally I think we could just make the next release of subunit say minimum testtools 0.9.13 (not yet released) and ditch the compatibility workarounds.

4 shell tests still fail due to test_function_output.sh not expecting time output.
