In we use "class Filename(str): ...", we have to ensure that all operations 
takes care of the charset because the unicode version is invalid and not be 
used to access to the file system. Dummy example: Filename()+"/" should not 
return str but raise an error or create a new filename.

If Filename has no parent class but is convertible to bytes(), os functions 
requires no change and so we can fix it before final 3.0 ;-)
