My bad, I forgot to put the Strikeout element in a table, i.e., to
wrap it in curly braces.

``` lua
function Plain (plain)

  local done_marker = pandoc.List{pandoc.Str '\u{2612}', pandoc.Space()}
  local prefix = pandoc.List{plain.content[1], plain.content[2]}

  if prefix == done_marker then
    plain.content:remove(2) -- remove space
    plain.content:remove(1) -- remove checkbox
    pandoc.Strikeout(plain.content)
    plain.content = done_marker .. {pandoc.Strikeout(plain.content)}
  end

  return plain
end
```
