If you're wondering how to check any packaging code files do not include any malicious code? You don't have to review the diff of all of them.
Usability of that script is not great yet. Just a dev tool.
There is a function diff_common_packaging_files. You can comment it in.
It'll loop through all the packages and compare if the makefile(-helper) of any package matches the makefile(-helper) of anon-apt-sources-list. So if you have checked anon-apt-sources-list and packaging-helper-script to be non-malicious, it's easy to verify all those files are non-malicious.
