Is errno.ENOENT the right value?

Oh, of course!!!!

Yes, which is puzzling.  Why would:
     os.listdir(path)
throw a WindowsError for something like 'path not found'.  Surely that's rather
a vanilla error, not at all specific to Windows?  Wouldn't an exception of
os.error with a code of errno.ENOENT make writting portable code just a bit
easier?

Appologies if my newbie-ness is getting in the way of me seeing something
obvious.
