Here is v7 with a stab at docs; fairly minimal at this point, but
touching the two areas that are likely to need adjusting.  When
adjusting the docs for sql-select, I noticed that the grammar also
supports `GROUP BY ALL <grouping_elements>`, so I also added a test to
ensure that this syntax is explicitly supported. (It seems like it
works as-is without further grammar adjustments, but I was a little
worried when I first saw that fact... :D)  Not sure that
aggregates.sql is still the right place for all of these bits, but it
does seem like having all things `GROUP BY ALL`-related tested in the
same place is a nice property, so leaving there for now.
