ptipython doesn't honor prompt_style = 'classic'

[kernc]

ptipython doesn't honor setting repl.prompt_style = 'classic' in config.py.

Use case: want to use ipython's extended features (i.e. magics), but have the prompt still look simple >>> and with easily copypastable output.

[kernc]

Even when ptipython is set to ipython style, it doesn't honor IPython's %doctest_mode magic.

Commenting out this line should solve your problem.
(Not sure why the override is there in the first place.)
