They are added. And we cannot easily distinguish between this and

  getfoo (i : int) : int \
  requires i >= 0 && i < 5 otherwise throw
System.ArgumentOutOfRangeException (i.ToString ())
    def x = array [1,2,3,4];
    printf ("%d\n", x [i]);
    x [i]


I don't know what would be the rule allowing to ommit \ in above example.

BTW. it works quite nice beside this problem with multiline headers,
where \   is needed.
