Technically interdiff can still be used. Esspecially when comparing
3.0 against 3.0. If the orig.tar and orig-component.tar files are the
same it could untar only the debian.tar, diff the debian dir but
interdiff the debian/patches/*

Optimizing the 1.0 vs 3.0 compare so it doesn't unpack the orig.tar is
probably wasted effort. How often does one do that?
