[common] Exceedingly common error induced in many ways, such as by
starting at 0 when you should have started at 1 or vice-versa, or by
writing < N instead of <= N or vice-versa. Also applied to giving
something to the person next to the one who should have gotten it.
Often confounded with {fencepost error}, which is properly a
particular subtype of it.
