[python-win32] Excel sort error with Python 2.2.3 & earlybinding

[Charlton, Craig A Ctr SMC/ISA]

I ran my test with the 'optional' arguments defined as pythoncom.Missing
and it does work now. Previously my code was working under a very old
Python 1.5.2 where the 'defaultNamedNotOptArg' was defined as
pythoncom.Missing in the .py file generated for the Excel 11.0 Object
Library. 

Evidently the more recent Pywin32 for 2.2.3 has defined these optional
arguments as pythoncom.Empty and thus the error was occurring. I expect
there was some rationale for changing the defaults, but it seems an
'optional' argument would want to use Missing rather than Empty. I'm not
an expert by any means though, so will do what works.

Thanks for pointing out the solution to my problem.
