   add_cmd() is called on each line of sed command text (from a file or from
   the command line).  It calls get_address() and parse_cmd_args().  The
   resulting sed_cmd_t structures are appended to a linked list
-  (sed_cmd_head/sed_cmd_tail).
+  (bbg.sed_cmd_head/bbg.sed_cmd_tail).
 
   add_input_file() adds a FILE * to the list of input files.  We need to
   know all input sources ahead of time to find the last line for the $ match.
