Queries are incorrectly joined back together resulting in syntax errors

[joereynolds]

Steps to reproduce

With this query

  SELECT AVG(Price), Manufacturer
      FROM Products
GROUP BY Manufacturer;

It will fail as it is joined back together as

 SELECT AVG(Price), Manufacturer      FROM ProductsGROUP BY Manufacturer;

Whereas it works fine with
(Note the space before GROUP

  SELECT AVG(Price), Manufacturer
      FROM Products
 GROUP BY Manufacturer;

It will be joined back together as

 SELECT AVG(Price), Manufacturer      FROM Products GROUP BY Manufacturer;

Actual behaviour

  SELECT AVG(Price), Manufacturer
      FROM Products
GROUP BY Manufacturer;

is joined as

 SELECT AVG(Price), Manufacturer      FROM ProductsGROUP BY Manufacturer;

Expected behaviour

The query is joined back as

 SELECT AVG(Price), Manufacturer      FROM Products GROUP BY Manufacturer;

It looks like the logic for this is in the putContentIntoLines function
