Sorry for the delay.

I am ready to commit your patch to emacs-26 with very minor changes:

1. The defcustom python-flymake-command-output-regexp is renamed to
python-flymake-command-output-pattern.

2. The docstring of that variable is slightly changed.

3. The function python--flymake is renamed python-flymake, since it is
public to python.el (there was some misunderstanding caused by me
earlier).

4. The commit message is very slightly changed so that the description
sentence starts on a line by its own.

Please verify,
João
