I probably misspoke a bit. The `Everyone'...`Everyone' owner and group appear
only on `..', and only when `..' represents the top level: c:\. And for Dired in
c:\ itself there is no `.' entry, so I can't say it contradicts what `..' showed
one level down (`Everyone'...`Everyone').

The bug, as I see it, is that `..' is different (showing
`Everyone'...`Everyone') _only_ for a directory just under c:\ - for example,
Dired in c:\foo\. Everywhere else, I see the same thing for `..' that I see for
every other file or directory (my user name and `None', in my case).

I see. But I do not in fact see the same thing in Emacs 22 as in Emacs 23, so
you must be doing something different in this case.
