Hey,

I _think_ we are having an issue in zuul job, which just uses old tox syntax for dumping the configuration.

So potentially, smth like [1] should be fixing the issue while preserving the expected behavior.

As `tox config -e py3` is dumping the config as expected, while `tox --showconfig -e py3` is crashing.

Hi,

Started seeing tox failures in pep8/docs/unit and some other jobs:

AttributeError: 'Parsed' object has no attribute 'config_format'

Melanie Witt provided some info at [0][1], I opened a bug [2] as it
seems like it was caused by a recent commit.

I would hold rechecks until someone confirms it's fixed.
