Subject: i5 nslookup bug

The "view" command in /usr/sbin/nslookup on i5 blows up, because it gives
an illegal argument to sed.  To elicit the bug, simply say

nslookup
server dns1.belwue.de
ls urz.uni-heidelberg.de > outfile
view outfile
sed: command garbled: /^$/,${/@/,$d}/^[^	]/{hs/^\([^	]*	*\).*/\1/x}1,/^$/{w /var/tmp/nslookup_tmpLga4IXd}/^	/{Gs/^	*//s/^\(.*\)\n\(.*\)$/\2\1/}

To make the sed command legal, we would have to insert the following twelve
newlines into the first argument that nslookup gives to sed:

/^$/,${/@/,$d
}
/^[^	]/{h
s/^\([^	]*	*\).*/\1/
x
}
1,/^$/{w /var/tmp/nslookup_tmpLga4IX
d
}
/^	/{G
s/^	*//
s/^\(.*\)\n\(.*\)$/\2\1/
}

Would it be possible to do this?  Thanks.
