FYI, I put a up-to-date version of the patch online at:
http://people.ubuntulinux.org/~mvo/pdiffs/apt-incremental-package-diffs7 

(against the arch archive at
http://people.debian.org/~mdz/arch/apt@packages.debian.org)

It contains some fixes for the previous patch.

Please note that a empty diff file:
gzip -c > Packages_diff_`md5sum Packages|awk '{print $1}'`.gz" < /dev/null
marks the last patch.

thanks,
 Michael
