 In WP 3.6 RC2, get_url_in_content($content) in wp-includes/formatting is
 {{{
 function get_url_in_content( $content ) {
         if ( empty( $content ) )
                 return '';

         if ( preg_match( '/<a\s[^>]*?href=([\'"])(.+?)\1/is', $content,
 $matches ) )
                 return esc_url_raw( $matches[2] );

         return false;
 }
 }}}

 I propose to add filter for the return value.

 {{{
         return apply_filters( 'get_url_in_content', false);
 }}}

 This filter will be useful in cases like this;
 "when no image found, I want to return a default image (site logo or
 something)"
