Comment 21 for bug 958987

I've just verified my conjecture at the end of the last message. I patched python-mode.el (r927) as follows:

--- python-mode.el.r927 2012-04-08 21:04:09 -0700

          (file (concat (expand-file-name temp py-temp-directory) ".py"))
          (filebuf (get-buffer-create file))
          ;; (process-connection-type 'pty)

Now when I run experiment 2, I get the following message:

Wrote c:/temp/c!!python27!Scripts!ipython.bat12188rll.py

Not maybe the most elegant solution, but at least it works.
