This patch displays an error when the node is not found, and redirects
the user to admin, since they can't administer a node that dosn't exist

When I go to /admin/node/book I get a completely blank page. I've looked
into book.module and if I modify the book_admin function to initialise
$output with any character (a space in the code below) then the page is
displayed "The book module offers a mean to organize content, authored
by many users, in an online manual, outline or FAQ." . As soon as I
take it out or make it $output = ''; the page again is not displayed.

Why is this? How is book_help being called to display the help message

function book_admin($nid = 0) {
  $op = $_POST['op'];
  $edit = $_POST['edit'];
  // KJP - if I don't add this the page is never displayed (NO
output) for /admin/node/book
  $output = ' ';
  switch ($op) {
    case t('Save book pages'):
      drupal_set_message(book_admin_save($nid, $edit));
      // fall through:
       $output .= book_admin_view($nid);
  return $output;
