Wow, Unicode filename support. Right this morning I had problems trying 
to convert latin-9 filenames to utf-8, and I couldn't do it with a quick 
python script because (now ) os.path.supports_unicode_filenames is False 
(in 2.3) even if right now I have unicode filenames and they seem to 
work OK. :-)

Is this a bug, or is it me not understanding something?

I think that if you have no compelling reasons to support 2.2, maybe you 
can spare yourself the effort :-)
