It also hooks GDB's readline wrappers (command_line_input) to Python so that line editing and history editing works. Additionally, Python's standard readline module is stubbed out because it conflicts with GDB's use of readline.

There already is an established behaviour for python without arguments
(with or without a terminal).
(gdb) python

I've read the thread and I don't seen anyone raising this issue (could
have missed it though. I saw Tom's message re: what output CLI will
generate, but this is about behaviour).
I've read the patch and I don't think using from_tty is ok to select
between the different behaviours.
Can we pick a different way of invoking the python interpreter?
