 `get_the_title()` has a workaround for when an invalid post ID is passed,
 setting the title to an empty string and post ID to the requested ID, then
 passing this to 'the_title' filter.

 '''Example:'''
 {{{
 function testme() {
         var_dump( get_the_title( 99999 ) );
 }

 function filterme( $title ) {
         return "[$title]";
 }

 add_action( 'wp_head', 'testme' );
 add_filter( 'the_title', 'filterme' );
 }}}

 Is there a reason for this odd functionality?
