Subject: bug#7368: 23.2; Python interpreter buffer should never appear in separate frame

From: Andrey Paramonov <[email-masked]>

Hello!

Most of the time, python-switch-to-python splits current frame and
activates Python interpreter buffer in a new window. This is handy and
consistent with other interpreter modes, i.e. ESS.

However, *sometimes* Python interpreter is activated in a separate
frame. This is very inconvenient, especially because of
"sometimes". Python interpreter buffer should always appear in the
current frame, and never in separate frame.

To reproduce:

0) emacs -Q

1) Create/open the following minimal example (| shows cursor pos):

import os.path

os.path.|

2) Press C-c C-z. Python interpreter buffer appears *in a new
window*. This is correct.

3) Switch to python code buffer, press ESC-ESC-ESC.

4) Press M-Tab. Completion buffer appears in a new window. This is
correct.

5) Press C-c C-z. Python interpreter buffer pops up *in a new
frame*. This is incorrect.

I'm ready to provide any additional info,
Andrey Paramonov
