Syntax cleanup in simpletests

I'm not sure what exactly the right format is (it's not mentioned in the coding standards), but it looks like some more lines could use some wrapping.

502:    $id = db_insert('test_one_blob')->fields(array('blob1' => $data))->execute();
566:    $query = db_insert('test')->fields(array('name' => 'Bob'))->useDefaults(array('job'));
635:    $num_updated = db_update('test')->fields(array('job' => 'Musician'))->where('age > :age', array(':age' => 26))->execute();
802:    $id = db_insert('test_one_blob')->fields(array('blob1' => $data))->execute();
805:    db_update('test_one_blob')->condition('id', $id)->fields(array('blob1' => $data))->execute();
822:    db_update('test_two_blobs')->condition('id', $id)->fields(array('blob1' => 'and so', 'blob2' => 'is this'))->execute();
904:    db_merge('test_people')->key(array('job' => 'Speaker'))->fields(array('age' => 31, 'name' => 'Tiffany'))->execute();
921:    db_merge('test_people')->key(array('job' => 'Speaker'))->fields(array('age' => 31, 'name' => 'Tiffany'))->updateExcept('age')->execute();
938:    db_merge('test_people')->key(array('job' => 'Speaker'))->fields(array('age' => 31, 'name' => 'Tiffany'))->update(array('name' => 'Joe'))->execute();

The list was generated using this command:
egrep -n "\)->(fields|condition|execute|where)" modules/simpletest/tests/database_test.test | egrep ".{81}"

The syntax clean-up in the patch looks good, but since c960657 implies there is more to be done, the patch should probably be expanded.

Looks as if this got already in somehow.
