I don't really like the idea, but I can see this being a compromise to cover
your use case. Yet in your reply to Nick you indicate you might go the route
he proposed, which I understand would allow us to get away without any such
option. If, however, an option is still needed from your pov, then please
make its name more meaningful than just "add-newline" - that doesn't tell at
all what the real purpose is. Maybe "separate-<whatever>", with <whatever>
suitably replaced, and then possibly also (in the future, not necessarily
right now) allowing to specify a character to use as the separator in place
of the (default) newline.
