Issue of the Standard # S0701

Brief

Inconsistency between formal definition of list in Shell Language Grammar and its informal description

Detailed Description

The informal description of a list in section 2.9.3 Lists reads: "A list is a sequence of one or more AND-OR lists separated by the operators ';' and '&' and optionally terminated by ';', '&', or <newline>".

The formal definition of a list is as follows:

list             : list separator_op and_or
                 |                   and_or
                 ;
...
separator_op     : '&'
                 | ';'
                 ;

This definition corresponds to the first part of the description only: "A list is a sequence of one or more AND-OR lists separated by the operators ';' and '&'".
