That would look really awful (IMO) if the strings weren't intended to be
on separate lines (I use embedded newlines instead of joining them with
newlines in order to prevent blank lines whenever a certain filter isn't
used). In this particular case, they are, so even though it uses a lot
of whitespace, it does match the layout of its output.
