putting the semicolon of a DDL statement on the same line as a comment,
(2) avoids long expression, even when dumping a table with many columns, and
(3) avoids unnecessary quoting of the table name.  This fixes tickets
[c04a8b8a4f] and [232637c465].  
Shell change only; no changes to the SQLite core.
