Changes

  1. Change icomment to:
    It has come to light that some legacy Android applications are coded
    with queries that are logically equivalent to this:
    
    <blockquote><verbatim>
    CREATE TABLE t1(a,x);
    CREATE TABLE t2(a,y);
    SELECT t1.a AS a, x, y FROM t1, t2 GROUP BY a;
    </verbatim></blockquote>
    
    The original fix for this ticket (see check-in [f2d175f975cd]) caused such
    queries to give an error:  "ambiguous column: a".  The query is indeed 
    incorrect.  Nevertheless, we need to find a way to get SQLite to run and
    return the correct result even for these incorrect, legacy queries.
