9.10.3 Address expansion

         All addresses in a CC list can be entered in short form, and
         several macros are recognized.

             cc: MYNET

         Will process your whole net and add every system to the CC
         list. Note that the previously supported notation
         "MYNET/node" (eg. MYNET/12) is no longer supported.

             cc: 2:310/*, 1:135/*

         Will include all systems in net 2:310 and 1:135.

             cc: 2:270/17.*

         Will include all listed point systems under 2:270/17.
