I have a hard time understanding how this would not reproduce, as (buffer-substring-no-properties prompt-end (point-max)) clearly takes all of the text (multi-lines included) from the prompt onward. I took a look here (python-mode v0.27.1) and the input is gathered in the same manner in the post-command-hook. The “repeated” lines in #6 are in the *Python-font-lock* buffer, btw.
