multiple line comma-separated values in INIs handled incorrectly

[bartekbrak]

setup.cfg could also fit within 79 chars, but it is hard when you have many paths to, let's say, exclude:

[pep8]
exclude = long/path/numero1,long/path/numero2,long/path/numero2,long/path/numero3,long/path/numero4,long/path/numero5,long/path/numero6

Most INI parsers allow this:

[pep8]
exclude = long/path/numero1,
    long/path/numero2,
    long/path/numero2,
    long/path/numero3,
    long/path/numero4,
    long/path/numero5,
    long/path/numero6

Not yours:

... 
print options.exclude
['/home/user/project_name/long/path/numero1', '/home/user/project_name/\nlong/path/numero2', ...]

Simple fix:

diff --git a/pep8.py b/pep8.py.org
index dca355b..2823f5b 100644
--- a/pep8.py
+++ b/pep8.py.org

That diff looks reversed.

That diff is reversed, plus it's not quite the right fix since it doesn't handle the case where the path has no /, but does have whitespace before or after the string.

I threw together a PR with tests.
