SET LIST-INCLUDE-HEADERS YES/no  -  whether the LIST command shows headers

With the usual YES setting, the output of the LIST command will include
  at the beginning a table of contents similar to the display of the 
  HEADERS command.  

If you change it to NO, the table of contents does not appear.

For more help, type "help" and one of the following:
(at any prompt:)  save-init   set   show   list
