Revision c90cda9300ddee21f1cdae1cd857da3a3c71dda3 authored by Fred Drake on 11 June 2002, 02:58:26 UTC, committed by Fred Drake on 11 June 2002, 02:58:26 UTC 
Completely revise markup for the list of list methods; the new markup matches
 
the semantics and presentation used in the library reference.
Added an explanation of the use of [...] to denote optional arguments, since
this is the only use of this in a signature line.
Closes SF bug #567127.
