Comment 8 for bug 534026

> Ah. Personally I don't like packages which change the packaging system to Debian for such a simple reason (since it creates large deltas like this), but with my -release hat on I don't object to it formally.

Adding one line to debian/source/format instead of hacking debian/rules is less error-prone and makes the diff file cleaner. Sadly the Debian package has direct source changes. The cleaned debdiff should work, too.
