By "symmetric difference", we mean a "set difference" operation that is symmetric. Contrasting with asymmetric difference that gives a set of elements that belong to set A but do not belong to set B (i.e. B..A), symmetric difference of set A and set B gives a set of elements that belong to either set A alone or set B alone but not both (i.e. A...B). So if you really want a fully spelled name, we would not want to call it with a name with "range". It is "symmetric set difference", and "symmetric difference" in the updated sentence is a short-hand for that. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
