bug#17370: 24.3.90; user cannot disable inferior python run from python-mode when file is visited

[Andy Moreton]

Load a file containing python code, in a file with extension ".py". This
will use python-mode as the major mode, which immediately runs an
inferior python executable.

I did not ask for a python interpreter, and do not want one running - I
just want to visit a file containing python code. There is not any
obvious way of disabling this behaviour.

Emacs should not run an arbitrary executable without explicit user
configuration to enable it.
