REVISION SUMMARY
  When a single query is streamed, the fields may be separated with multiple
  spaces, while subqueries, which are streamed via recursion from QVector,
  may lack any spaces between fields.
  
  Disable any automatic insertion of spaces and add delimiters manually
  where necessary.
