It would be easier to have a pythonw2.exe where this feature is
built in, rather than a command line option.  But see below.

Well, that is the problem.  Is this feature "generally useful"?
I am writing Windows programs in which Python is the "main"
and provides the GUI, so I find this useful.  And I do show
my users tracebacks.  But perhaps this is unique to me.  I
don't see users of wxPython nor tkinter replying "great idea"
so maybe they don't use pythonw.

Absent more support, I don't think this idea has enough
merit to justify a patch.
