new nonterminal for storing lists of separator tokens in the parser * separator-list.h: New file. * libinterp/parse-tree/module.mk: Update. * parse.h, oct-parse.yy (sep_list_type): New nonterminal type. (sep_no_nl, opt_sep_no_nl, nl, opt_nl, sep, opt_sep): Declare as sep_list_type instead of punct_type. Update rules to create separator list objects instead of returning characters. In rules that use them, delete as yet unsaved separator_list objects. (punct_type): Delete now unused nonterminal type. (base_parser::set_stmt_print_flag, base_parser::append_statement_list): New overloads that accept separator token and separator_list objects. (base_parser::append_function_def_list): Accept separator_list instead of char. (base_parser::make_try_command): Update to use separator list instead of character.
