* parser.y (r_exprs): New grammar symbol. r_exprs uses
left-recursive rules to avoid filling the yacc stack, and
returns the items in reverse order. The output of each
r_exprs-generating rule consists of a list which gives
the terminating atom, and then the list contents in reverse order.
(n_exprs): Becomes wrapper for r_exprs which deals with
the terminating atom, and reversed items.
