----------------------------+-----------------------------
 This is my first bug report with a patch file, so please correct me if I
 have choosen something wrong.

 When '''SHORTINIT''' is used the '''wp-includes/formatting.php''' file is
 not included. Certain functions which are defined in this file are being
 used by other functions. So calling any of these functions throws a
 '''Fatal Error'''.

 === Examples: ===

 * ''sanitize_file_name()'' is called in '''wp-includes/functions.php''' by
 the function ''wp_unique_filename()''
 * ''sanitize_option()'' is called in '''wp-includes/option.php''' by
 several functions - ''add_option()'', ''update_option()'',
 ''add_site_option()'' and ''update_site_option()''

 === Reproducing this error: ===

 Create a file inside the WordPress installation directory with the
 following code.

 {{{
 <?php
 define( 'SHORTINIT', true );
 require_once $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php';
 var_dump( add_option( 'foobar', 'Hello World' ) );
 ?>
 }}}

 Access this file on the browser and the following error is displayed
 (debugging should be enabled of course).

   Fatal error: Call to undefined function sanitize_option() in wp-
 includes/option.php on line 305

 === Workaround: ===

 Manually include the file in your code.

 {{{
 <?php
 define( 'SHORTINIT', true );
 require_once $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php';
 require_once ABSPATH . WPINC . '/formatting.php';
 var_dump( add_option( 'foobar', 'Hello World' ) );
 ?>
 }}}

 I have attached a patch which includes the formatting.php file before the
 SHORTINIT check.
