I don't feel a need to. 7.8 isn't attempting to define the syntax
precisely. Moreover, we've had this feature since 8.4, and this
is the first I've heard of somebody misinterpreting the syntax;
so it doesn't seem like it's a huge problem that requires multiple
explanations.
I've pushed a patch for the SELECT reference page.
