PEP8 conformance test fails without listing location of failures

[mdboom]

We are currently seeing this on master:

======================================================================
FAIL: matplotlib.tests.test_coding_standards.test_pep8_conformance

Yeah, this should definitely be improved. It is worth noting that the warnings which enumerate the exceptions are peppered inline with the test output, so it is there - just not very convenient...

I can't see the failing test on travis. Which build was it? (https://travis-ci.org/matplotlib/matplotlib/builds)

The problems look like:

Ok. I've just gone ahead and disabled this test in 3a3f28c for now. I think if we're going to do this as a full on failure, the messages need to be prominent and easy to find. Once we've resolved this, we can re-enable this.

I am closing this as the errors look useful to me now and it looks like #2099 fixed this.
