About Group Lines
Lines are gathered under whatever they have in common at the start - everything before a separator, or the first few characters. Groups appear in the order they were first seen, with their members in the original order.
Good for sorting a flat list into sections: hostnames by region, files by extension, IDs by their prefix.
