Side note: !!! I didn't know pandoc Lists could be concatenated with `..`, 
that's great! Is this a recent addition to the Lua filter module? Would be 
great to document it 
(https://pandoc.org/lua-filters.html#pandoc.list:__concat). Happy to submit 
a PR, but not sure whether small PRs on Pandoc's documentations are 
welcome.
