[j-nsp] | display inheritance vs. logical-systems

[Chuck Anderson]

An interesting CLI bug:

"show configuration | display inheritance" doesn't find prefix lists
that are referenced via configuration groups that are applied inside a
logical-system, but the configuration commits and works correctly:

MX_RE0# show groups DROP-RESERVED-SOURCES 
logical-systems {
    <*> {
        firewall {
            family inet {
                filter <*> {
                    term DROP-RESERVED-SOURCES {
                        from {
                            source-prefix-list {
                                RESERVED-ADDRESSES;
                            }
                        }
                        then {
                            count DROP-RESERVED-SOURCES;
                            discard;
                        }
                    }
                }
            }
        }
    }
}

MX_RE0# show logical-systems LSYS1 policy-options prefix-list RESERVED-ADDRESSES 
10.0.0.0/8;
172.16.0.0/12;
192.168.0.0/16;

MX_RE0# show logical-systems LSYS1 firewall family inet filter CUST-IN 
apply-groups DROP-RESERVED-SOURCES;

MX_RE0# show logical-systems LSYS1 firewall family inet filter CUST-IN | display inheritance 
##
## 'DROP-RESERVED-SOURCES' was inherited from group 'DROP-RESERVED-SOURCES'
##
term DROP-RESERVED-SOURCES {
    ##
    ## 'from' was inherited from group 'DROP-RESERVED-SOURCES'
    ##
    from {
        source-prefix-list {
            ##
            ## 'RESERVED-ADDRESSES' was inherited from group 'DROP-RESERVED-SOURCES'
            ##
            RESERVED-ADDRESSES; ## 'RESERVED-ADDRESSES' is not defined
        }
    }
    ##
    ## 'then' was inherited from group 'DROP-RESERVED-SOURCES'
    ##
    then {
        ##
        ## 'DROP-RESERVED-SOURCES' was inherited from group 'DROP-RESERVED-SOURCES'
        ##
        count DROP-RESERVED-SOURCES;
        ##
        ## 'discard' was inherited from group 'DROP-RESERVED-SOURCES'
        ##
        discard;
    }
}

Notice the comment "## 'RESERVED-ADDRESSES' is not defined".  It is
defined...
