They're separate but kind of clumsy to use together for line continuations.
`read' ends up calling readline N times for every N-1 backslash-escaped
newlines. If -r is supplied it doesn't need to do anything out of the
ordinary for \<newline>.
In terms of backslash escaping characters in the line read, backslash
isn't really special to readline, it's just mapped to self-insert. You
still have to use quoted-insert to insert characters that are bound to
line editing commands.
