Comment (by mordauk):

 Looks like `wp_sanitize_redirect()` also eats square brackets:
 https://core.trac.wordpress.org/browser/tags/3.9.1/src/wp-
 includes/pluggable.php#L1135


 Input:

 `wp_sanitize_redirect( 'http://localhost/wordpress/wp-
 admin/admin.php?var[]=test&var[]=test2' )`:

 Expected output:

 `http://localhost/wordpress/wp-admin/admin.php?var[]=test&var[]=test2`

 Actual output:

 `http://localhost/wordpress/wp-admin/admin.php?var=test&var=test2`
