run subcommand should take a module name
A la python -m <mod> switch, it'd be helpful to pass a the name of a module to cover, instead of just a file.
The use case here is integration with unittest's test discovery. As of 2.7 can do
python -m unittest discover and it will find your tests. There's no way AFAICT to simulate this correctly - trying to pass '/usr/lib/python2.7/unittest/init.py' as run's <pyfile> argument messes up import paths.
Currently, I wrote a little stub that just calls unittest's main(), but figuring this out how to do this was slightly annoying.
