[HACKERS] Unhelpful typesetting of callouts in example queries in the docs

Hi

A novice user asked me about the last example here, which kept producing errors:

https://www.postgresql.org/docs/9.6/static/tutorial-agg.html?

It turned out that the 'callout' was causing confusion because it
sticks "(1)" into the middle of the query in approximately the same
typeface:

SELECT city, max(temp_lo)
    FROM weather
    WHERE city LIKE 'S%'(1)
    GROUP BY city
    HAVING max(temp_lo) < 40;

Maybe we should move it over a bit (?) and make it a comment, in case
it gets copied-and-pasted or otherwise misinterpreted?

SELECT city, max(temp_lo)
    FROM weather
    WHERE city LIKE 'S%'           -- (1)
    GROUP BY city
    HAVING max(temp_lo) < 40;

See attached which does that and there and a couple of other places.
