It's one of those marginal ones I think,
but if you think it's warranted, that's cool.
I would use the more consistent option for this though, i.e.:

  -z, --zero                    end each output line with NUL, not newline

We could document that -z implies:

  --quoting-style=literal --show-control-chars --format=single-column

The --format=single-column implication is debatable.
I'm suggesting it as robust programmatic parsing of --format=long is
pretty much impossible, which is not obvious.

thanks,
Pádraig
