Wishlist

I have emacs set up to indent Python code like so (I don't actually
recall what I did to configure the position of the closing parenthesis,
but I have python-indent and tab-width set to 4):

foo(
    bar, baz
)

That works fine. However, that style in a particular program I'm working
on very often means I find myself with text like this:

some_very_long_python_function_call(an_extremely_long_name_here,
and_another_one_right_here)

At which point I'd like to be able to ask emacs to reformat that line,
or sexp if you like (the one at point, let's say), like this:

some_very_long_python_function_call(
    an_extremely_long_name_here, and_another_one_right_here
)

or sometimes like this:

some_very_long_python_function_call(
    an_extremely_long_name_here,
    and_another_one_right_here
)

Just using regular editing keys I find this a bit of a chore.

It would be really great if there were a command to do this (I guess in
python.el).


I will note that it is also fairly often the case that the reason I want
to split a function call across multiple lines is not that the line
would be too long, but that there are many arguments, so this is better:

do_something(
    foo,
    bar,
    baz,
    ham=3Dspam
    potatoes=3Dvegetables
)

than this:

do_something(foo, bar, baz, ham=3Dspam potatoes=3Dvegetables)

just because I find the former is easier to read.

Finally, in some cases the parenthesized expression to be broken over
lines is something other than a function call (e.g. an import list or
tuple -- or even a list, not strictly a parenthesized expression, but
similar).
