Support multi-line options in setup.cfg

When specifying excluded files in setup.cfg, all files need to be comma separated and on the same line. Version 2.3.0 is able to handle these comma separated files on multiple lines, version 2.4.0 isn't.

setup.cfg without multi-line:

[flake8]
exclude=spam,eggs,beans

setup.cfg with multi-line:

[flake8]
exclude=
    spam,
    eggs,
    beans

As an extra, the comma in the multi-line config is pretty useless. If it's possible, also make the comma optional.

Could you please provide the full output from flake8 --version on 2.3.0 and 2.4.0?

2.3.0:

2.3.0 (pep8: 1.6.2, pyflakes: 0.8.1, mccabe: 0.3) CPython 2.7.9 on Linux

2.4.0:

2.4.0 (pep8: 1.5.7, pyflakes: 0.8.1, mccabe: 0.3) CPython 2.7.9 on Linux

Interesting that a newer version of flake8 uses an older version of pep8.

That's documented in #51.

That aside, the config parsing is handled in pep8. This will regress with 1.6.3 (or whatever the pep8 maintainer actually releases).

This request should be made there.

Since the config parsing works as expected when using pep8 1.6.2 and not with 1.5.7, I don't see the point in reporting an issue. The developers of pep8 will probably advise to upgrade.
flake8 2.4.0 uses an older version of pep8, so it seems like a regression at first, it actually is a downgrade. My guess is that flake8 should depend on a newer version of pep8 instead of an older version. If flake8 would depend on pep8 1.6.2 (or newer) the problem is solved. So I believe the issue should still be filed here.

Please do some research into the issues described in #50 #37 and probably a few others (perhaps #48). The currently released branch of 1.6.x is very broken. We're restricting the version to give the best experience to the largest percentage of our users. If you want to use broken versions of pep8, pin to flake8 2.3.0. pep8 recently reverted the config changes they made which broke the 1.6.x series but they have not released a version that fixes the above mentioned issues.

We did not introduce any bugs. You should, therefore, be registering your complaints with the pep8 project.

I see, point taken. Thanks for the explanation.
