Emacs is behaving as documented.
The `su' programs from coreutils (it's since been removed in favour of
the util-linux one) and util-linux (as used by eg Red Hat) do not change
LOGNAME or USER when su'ing to root.
It seems that Debian's `su' comes from the `shadow' package and does
change them.
But all the `su' programs are behaving as documented too.
It's a shame they don't agree with each other...
