Merge branch 'master' into staging

gnu: Add comments to the bottom of a few package modules.

This will hopefully discourage patches which add new packages to the bottom of
files, as this increases the likelihood of conflicts when applying patches.

If there are more specific ways that packages should be arranged in specific
modules, this message can be updated accordingly.
