python-mode patch

[Slawomir Nowaczyk]

Hello,

I would like to suggest the following patch for python-mode.

The intend is to make commands like python-send-buffer execute files
in the global namespace of the "main" script, not within namespace of
the "emacs" module.

An example: currently, if you run python-send-buffer in a buffer
containing "x=1", a python interpreter will open and execute the
assignment, but trying "print x" will fail. One needs to type,
instead, "print emacs.x". All functions, classes, variables etc.
defined in the buffer will end up in a namespace of "emacs" module.

After my patch, "print x" does work (note that I only have python
2.4.3 so I only tested there, but I think older versions should work
similarly).

For me, personally, this is a serious bug which makes python-mode
almost unusable. Did anybody actually liked the way it used to work?
It would be sufficiently easy to provide an option here, but I do not
think it makes sense.
