+1. as predicted there was an error in the Prefix routine, I have improved it.
+24Jun02=======================================================================
+1. make set/badspotter non SSID sensitive. Set/badnode is left to be SSID
+sensitive.
+2. added 3XA(=3X) and K1B(=KH1) also changed the logic of sh/prefix. This
+may break things, please test it.
