Sorry, should have tried -Q.  Turns out the tutorial was read-only
because I had dir-locals that set a directory to read-only and I
happened to run `C-h t' from that directory.

Try with,

    emacs -Q
     '((nil . ((buffer-read-only . t)))))
    (dir-locals-set-directory-class default-directory 'unwritable-directory)
    C-h t

I believe I've found a corner-case.

Although, is (hack-local-variables) really that necessary in
tutorial.el?  It's not clear to me.
