It looks as if the advice I gave below may only be valid for
sources.list. I apologise if I was misleading, but see further discussion.

Thanks for the correction/clarification. I thought I understood,
but now I know I don't.
Is it that "sid" and "unstable" mean the same on /etc/source.list,
because the two names are permanently paired off
(unlike "woody"="stable", which became false recently),
but they have different meaning or validity in apt.conf
and apt/preferences?
