It is unclear to me if this is a deficiency of > dpkg-maintscript-helper or the caller. I guess it's a bit of both. I consider the current behavior in dpkg-maintscript-helper to be a bad default optimized for the wrong thing, which I'll try to fix before checking that this will not incur much fallout. But as it stands this is bad usage from the package affected. Merging with the rest. Thanks, Guillem
