True when String represents Lines. This follows
the normal text convention that a line is defined as a possible empty
string followed by a newline character ("
?- string_lines("a\nb\n", L).
L = ["a", "b"].
?- string_lines(S, ["a", "b"]).
S = "a\nb\n".
This predicate is a true relation if both arguments are in
canonical form, i.e. all text is represented as strings and the first
argument ends with a newline. The implementation tolerates non-canonical
input: other types than strings are accepted and
String does not need to end with a newline.

split_string(String, "\n", "", Lines) on a string
that ends in a newline adds an additional empty string compared to string_lines/2.
