Huh?  Why a newline?  Control J *is* a newline char.

Instead of treating that as an aberration or some secret
incantation, we should (and we do, for the most part)
simply make the Control J <=> newline relationship, and
hence `C-q C-j' for insertion, known from the outset.

Emacs users, like GNU/Linux users in general, should be
aware of this, if they make explicit use of newline chars.

You can distinguish the key `C-m' from the key `<return>',
but you cannot distinguish the character Control M from
the character CR (carriage return) - by definition.
