If we are going to be upgrading dpkg so that it handles new compression 
formats, could we also change the way the dpkg utils compress data.tar and 
control.tar so that it uses an official and documented version for each 
compression utility it uses. 

For example, could the new dpkg utilities generate all data.tar.gz files be 
using the command:
	gzip-1.3.5 --best -N < data.tar > data.tar.gz

Apart from saving ~1Kb per deb file, this would also make it *much* easier to 
do tricks like Deb-diffs.

Perhaps the new Debian version number could be a x.y.z number where z is only 
used by patch utilities that need to know exactly how to regenerate a deb 
file with the same md5sum?
