Comment:

 @peterwilsoncc I just pulled the patch and ran the option unit tests and
 they passed.

 `phpunit tests/phpunit/tests/option/option.php `

 The method **test_the_basics** asserts this to false if the value is the
 same.

 ` $this->assertFalse( update_option( $key, $value ) );  // Value is the
 same `
