191*0Sstevel@tonic-gate * ``system!name'', which means there is a two part matching
192*0Sstevel@tonic-gate * for ``all'' cases (all systems and/or all names). Second,
193*0Sstevel@tonic-gate * ALL matching items in the list are deleted.

195*0Sstevel@tonic-gate * Now suppose the list contains just the word ``all'', and
196*0Sstevel@tonic-gate * the item to be deleted is the name ``fred''. What will
197*0Sstevel@tonic-gate * happen? The word ``all'' will be deleted, leaving the list
198*0Sstevel@tonic-gate * empty (null)! This may sound odd at first, but keep in mind
199*0Sstevel@tonic-gate * that this routine is paired with the regular "addlist()"
200*0Sstevel@tonic-gate * routine; the item (``fred'') is ADDED to an opposite list
201*0Sstevel@tonic-gate * (we are either deleting from a deny list and adding to an allow
202*0Sstevel@tonic-gate * list or vice versa). So, to continue the example, if previously
203*0Sstevel@tonic-gate * ``all'' were allowed, removing ``fred'' from the allow list
204*0Sstevel@tonic-gate * does indeed empty that list, but then putting him in the deny
205*0Sstevel@tonic-gate * list means only ``fred'' is denied, which is the effect we
