Hi John!

  I'm surprised you didn't chastise me until I produced a better example
that fully demonstrates the obscure corners in this area <wink>.  For
example, the open() builtin (plus many other related functions) natively
support Unicode strings and calls the unicode versions of the underlying
Microsoft C runtime functions.  The following demonstrates this, and doesn't
rely on an already existing file:

>>> open(u"c:\\temp\\\xa9opyright someone.txt", "w").write('hello there!')
>>> win32api.GetShortPathName(u"c:\\temp\\\xa9opyright
>>> open('c:\\temp\\OPYRIG~1.TXT').read()
'hello there!'

In this example, pywin32 is the 'weak-link' in the Unicode story - and that
doesn't sound like something we can let stand - so I just checked in a
change that if win32api.GetShortPathName() is passed unicode, it calls
GetShortPathNameW and returns a unicode object.  So in the next build, you
will see:

>>> win32api.GetShortPathName(u"c:\\temp\\\xa9opyright someone.txt")
