bug#16875: python, comint-mode: Large output makes Emacs freeze

[Andreas Röhler]

May confirm what is reported here:

Form sent is

[[[False] * 200 for i in range(3)] for j in range(200)]

Does only occur with plain Python-shell, not if IPython is running.

IIUC that's because IPython return is passed through a kind of pretty-print, 
inserting newlines.

Comints dealing with long lines seems the cause.

With process-send-string it works.
