bug#70874: Don't use two column Info examples, e.g. for join

[Dan Jacobson]

I would say please give up attempting two column examples, e.g., on
(info "(coreutils) Paired and unpaired lines")

Yes, they look great in the standalone Info reader,
$ info

But in emacs -Q -f info
we start to see problems.

And then e.g., using https://www.jidanni.org/comp/configuration/.emacs
things look worse
