Then I misunderstood; would you explain what you mean in a different = way? The old text incorrectly stated that the return value always is a new = string; the last patch changes this to saying that the value may or may = not be a new string, and that the user therefore shouldn't assume that = the value be mutable. If that was not what you asked for, then what was = it, and why? > And how does mutability enter the picture?

Sorry, but I still don't understand. What salient quality is there other = than mutability? There is identity (uniqueness), but that is included as = well. No user is ever worried about that the returned value may actually = be a new string; it's very much the other way around.
