PEP8 alternatives how to close a list implemented, lp:1197521

Boolean `py-close-at-start-column-p', default is nil

my_list = [
    1, 2, 3,
    4, 5, 6,
    ]
result = some_function_that_takes_arguments(
    'a', 'b', 'c',
    'd', 'e', 'f',
    )

When non-nil, it will be lined up under the first character of the line that starts the multi-line construct, as in:

my_list = [
    1, 2, 3,
    4, 5, 6,
]

result = some_function_that_takes_arguments(
    'a', 'b', 'c',
    'd', 'e', 'f',
)
