Config silently ignored if nonexistent

The flake8 package silently ignores the configuration suggested by "--config" in case it can't access it.
That means that, in many cases, strange warnings may surface where there previously were none.

I would suggest a clear error message, like "Can't find and/or read the config file"

So this parsing is actually entirely handled by pep8. Can you please report this on that project instead? Thanks!
