Error on http://www.gnu.org/software/emacs/elisp/html_node/Auto-Major-Mode.html

[Decebal]

On this page there is the following code:
          (setq auto-mode-alist
            (append
             ;; File name (within directory) starts with a dot.
             '(("/\\.[^/]*\\'" . fundamental-mode)
               ;; File name has no dot.
               ("[^\\./]*\\'" . fundamental-mode)
               ;; File name ends in `.C'.
               ("\\.C\\'" . c++-mode))
             auto-mode-alist))

But the rule for a file name without a dot should be:
               ("/[^\\./]*\\'" . fundamental-mode)

Where should I tell this so that the error could be modified?


Also on some places end of the filename is written like \\' and on
other places like $. What is the difference between those two?
