		// -1 = unknown size
		// 0 is somewhat of a special case: Unlike c/image, where 0 is a definite known
		// size (possible at least in theory), in mpb, zero-sized progress bars are treated
		// as unknown size, in particular they are not configured to be marked as
		// complete on bar.Current() reaching bar.total (because that would happen already
		// when creating the progress bar).
		// That means that we are both _allowed_ to call SetTotal, and we _have to_.
		bar.SetTotal(-1, true) // total < 0 = set it to bar.Current(), report it; and mark the bar as complete.
