Function arguments - one per line

Wonderful plugin, I enjoy it a lot. Could you introduce an option to autocomplete function arguments one per line? Example:

turn this -> enumerate(iterable, start=0)
into      -> enumerate(iterable,
                       start=0)

This would be particularly useful for functions with a long signature such as pd.read_csv() in combination with “auto_complete_function_params”: “all”.

I personally don’t like that style of indentation for parameters because is fragile to break during refactoring. if you have

variable = a_function(bla1,
                      bla2)

and you have to rename variable or a_function you have to fix the indentation of the parameters one by one, and there could be a few of them.

Uncle Bob (Rob Martin) advises to use this way instead:

variable = a_function(
    bla1,
    bla2,
)

Adding trailing commas also, so in case you have to remove or add a parameter only one line is modified.
