Comment(by dd32):

 I'm still failing to see how this breaks anything, It now abides by what
 it was supposed to do.

 Furthurmore, Peoples plugins SHOULDNT break because of this.

 If you rely upon a false return from the function, as long as you havnt
 used typechecking, it still works, false == '', false == array(),
 empty(before()) == empty(after()), The logic stays the same, With the
 benefit that people can now safely use the function directly in themes (As
 it was originally intended IIRC).
