Update GROUP BY ALL comments about window functions When GROUP BY ALL was added in commit ef38a4d9756, the SQL standard working draft was silent on what to do with window functions. This has now been fixed in the SQL standard working draft. Update the documentation and code comments about that.
Also make the documentation more specific that we are only talking about aggregate functions referring to the same query level, which is another thing that has been made more precise in the SQL standard working draft since. The PostgreSQL implementation was already doing the right thing for both aspects, so no functionality changes.
