--------------------------------+-----------------------------
 In a multisite configuration the `get_site_option()` function in `wp-
 includes/option.php` does not cache `meta_key`s with `meta_value`s of
 empty strings resulting in a database query being run on every request.
 Checking for a `meta_value` matching an empty string to trigger an entry
 into the `notoptions` cache will correct this behavior.

 from:
 {{{#!php
 if ( is_object( $row ) )
 }}}

 to:
 {{{#!php
 if ( is_object( $row ) && $row->meta_value !== '' )
 }}}
