- Use os.makedirs (I had forgotten about it!)
- Let TempdirManager.write_file call os.path.join for us
- Remove custom command added by test_dist
- Use a skip instead of hiding a method with an underscore
- Address pyflakes warnings
I need this for some tests, and it makes code clearer. This commit also
changes some assertEqual calls to use (actual, expected) order and fix
some pyflakes warnings.
