 When called with no 'exclude' argument, wp_list_pages() passes an array
 with a nullstring element to the filter 'list_pages_excludes'.  If a
 plugin then adds at least one more element to that array, the result is a
 leading comma in the 'exclude' argument string which is passed to
 get_pages() and walk_page_tree().

 This misplaced comma does not affect WP core behavior.  But if a plugin
 which filters 'get_pages' copies the 'exclude' argument to 'exclude_tree'
 (logical enough if depth=1 is also passed) and mimics core handling of
 that argument, the result is exclusion of the Main Page (ID zero) and all
 its children.
