+reasons of efficiency, when listing killed groups, this specification
+is ignored altogether.	If the spec is changed considerably, your
+output may end up looking strange when listing both alive and killed
+groups.
+If you use %o or %O, reading the active file will be slower and quite
+a bit of extra memory will be used.  %D will also worsen performance.
