bug#57262: 29.0.50; Python indentation problem of block continuation

[kobarity]

Hi,

When you type the following code in the Python mode buffer and hit
Enter key, the next line will be indented with 4 spaces (assuming
`python-indent-offset' is 4).

#+begin_src python
for long_variable_name \
#+end_src

However, it is not appropriate because it will be "continuation line
with same indent as next logical line" error.  The indentation should
be one level deeper as follows:

#+begin_src python
for long_variable_name \
        in (1, 2):
    print(long_variable_name)
#+end_src

Attached is a patch to fix this issue.

Best Regards,
