Different rules for different type of braces

[Drachenfels]

Plugin is awesome and it works like a charm, however there is one small tweak that probably could make it even more awesome.

If we have this option on:

argwrap_tail_comma=1

We expect braces {} to be like that:

{
    'a',
    'b',
    'c',
}

We expect braces [] to be like that:

[
    'a',
    'b',
    'c',
]

But braces (), to be like that:

(
    'a',
    'b',
    'c'
)

Why?

In python we don't want to generally have this kind of definitions:

def some_function(
    a,
    b,
    c,
)

While it's not syntax and pep8/pylint don't complan about it either it's not widespread used coding standard. I imagine some other languages might be more strict about it.

So I would propose to allow define variable like that:

argwrap_tail_comma={,(,[

To maintain backward compatibility 1 means all types of brackets and 0 none.
