Message 111154 - Python tracker

The current behaviour on OSX for IDLE.app is to always open a shell window, and open edit windows for any files that should be opened during launch.

IDLE.app does not open an empty edit window, and I agree that this is sane behaviour.

One other thing that might be interesting to know: IDLE.app is already set up to open just a single instance of IDLE when users open python files from the Finder.
