Fixing Leo and Idle OS shutdown bug?

Hmm.  There are conflicting reports about what happens when Linux shuts down
and there are dirty files in Idle.

Yes, it does (at least, version 0.4) for the windows which are open by
``File->New Window'' or ``File->Open''. When you attempt to close such
window, you are asked for the confirmation.
``Python Shell'' windows can be closed without any confirmation from the
user.

support @ internetdiscovery.com (Mike Clarkson) says:

It's WM_DELETE_WINDOW for the normal program exit, but the OS shutting
down message is WM_QUERYENDSESSION  and  WM_ENDSESSION.
Problem is that wm_protocol doesn't catch either of these messages.

To change this you have to change Tk.  Attached is an old posting
requesting this change to Tk, but AFAIK it still hasn't been
implemented (sorry about the line wrapping).

Can anyone suggest a resolution?
