Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml
