Running with "run" argument considered ambigious

Not sure if this belongs here but right now running bench.py with run brings up this error. It seems like there's an active issue for this: https://bugs.python.org/issue14365

> ..\python_d.exe bench.py run
usage: bench.py [-h] {run,compare,run_compare,list,list_groups} ...
bench.py: error: argument action: ambiguous choice: 'run' could match run, run_compare
