[Emacs-diffs] master cbb8a8a 1/2: Fix fill-paragraph in python docstrings (Bug#36056)

[Noam Postavsky]

branch: master
commit cbb8a8ad979ed7975bfc7e9fa6aeeb4d9d6b7084
Author: Noam Postavsky <address@hidden>

    Fix fill-paragraph in python docstrings (Bug#36056)
    
    * lisp/progmodes/python.el (python-do-auto-fill): New function.
    (python-mode): Set it as normal-auto-fill-function, and don't set
    fill-indent-according-to-mode.  Having the latter set during
    fill-paragraph gives wrongs result, because python-indent-line doesn't
    remove indentation added by filling.
    * test/lisp/progmodes/python-tests.el (python-fill-docstring): New
    test.
