Thanks a lot for your help, which = enabled me to write the following short filter, which puts the name of all = authors on the same line in 'do= cx' output, while preserving the nice default layout in 'latex' output.
De= bugging filters working on the yaml metadata provided a particular challeng= e to me:

function Meta (m)
=C2=A0 if FORMAT:match 'docx' then
=C2= =A0 =C2=A0 =C2=A0 =C2=A0 authors =3D m.author[1] .. {pandoc.Str(', '= ;)} .. m.author[2]
=C2=A0 =C2=A0 =C2=A0 =C2=A0 m.author =3D pandoc.MetaI= nlines(authors)
=C2=A0 end
=C2=A0 return m
end
It only handles two and not more authors, but in my case, that= 's fine.

Your metadata has this structure (hmm... perhaps some of the Inlines are = really MetaInlines, in which case that's a problem with my logging modu= le):

(#) meta Meta {
=C2=A0 = author: List[2] {
=C2=A0 =C2=A0 [1] Inlines[3] {
=C2=A0 =C2=A0 =C2=A0= [1] Str "Author"
=C2=A0 =C2=A0 =C2=A0 [2] Space
=C2=A0 =C2= =A0 =C2=A0 [3] Str "A"
=C2=A0 =C2=A0 }
=C2=A0 =C2=A0 [2] In= lines[3] {
=C2=A0 =C2=A0 =C2=A0 [1] Str "Author"
=C2=A0 =C2= =A0 =C2=A0 [2] Space
=C2=A0 =C2=A0 =C2=A0 [3] Str "B"
=C2= =A0 =C2=A0 }
=C2=A0 }
=C2=A0 title: Inlines[1] {
=C2=A0 =C2=A0 [1]= Str "Test"
=C2=A0 }
}

= ... so I think you want this filter (MetaInlines isn't an attribute nam= e, and you have to count the space):

function Meta (m)
=C2=A0 =C2=A0 print(pandoc.utils.stringify= (m.author[1][3]))
end
