This is a bit different than what I was looking at, but there still
is a problem. I didn't know you could mix * and other expressions.
I now think the second line should be:
{* | expression [ AS output_name ]} [, ...]
What I was complaining about was that the first line was only included
on the left side of that alternation. However the above fix takes care
of that problem as well.
