Hi Gustaf,

Thank you for your suggestion.  I think this is more readable and
would like to make changes in this direction.

Just to be clear, what I wanted to express by "some items follow the
opening paren on the same line in a block statement" is that it only
works with the code like the following:

#+begin_src python
if ("VALUE" in my_unnecessarily_long_dictionary
        and some_other_long_condition_case):
    do_something()
#+end_src

And it does not work for the code like the following:

#+begin_src python
if (
    "VALUE" in my_unnecessarily_long_dictionary
    and some_other_long_condition_case):
    do_something()
#+end_src

This is intentional.  Because this code is usually written as follows:

#+begin_src python
if (
    "VALUE" in my_unnecessarily_long_dictionary
    and some_other_long_condition_case
):
    do_something()
#+end_src

In this case, there is no need for extra indentation.  As I wrote in
the previous mail, this case is processed by the existing code and can
be customized with `python-indent-def-block-scale'.

However, this may be a marginal difference.  In any case, I will wait
a few more days for other comments and hope to revise the patch over
the weekend.
