Not only that, but it's not clear why "that shouldn't have happened".
It's good to optimize away the whole add-text-properties when it ends up
doing nothing, but it's just an optimization.
And I don't think it's an important one here, since (as Dmitry points
out) the likely most common case (of having `start' be right at the
beginning of an interval object) didn't work anyway, and furthermore
most calls to add-text-properties are likely to be protected by
inhibit-modification-hooks.
