This would circumvent the "ask again" problem, but I think it is still
problematic: The admin is shown a diff between the new conffile and the
present conffile, but only the unimportant changes are shown, while the
important change has already been done by the preinst script.  This is
confusing - especially if the admin remembers his old file, or if one of
the unimportant changes is a change in a comment that says how important
the new setting is...

No, I think he simply missed the idea of doing the editing in preinst,
just like me - you never mentioned it before.
