Subject: 24.3; visual-line does not activate properly from file header
Date: Mon, 21 Oct 2013 13:53:46 -0600

When I add the following line:

    -*- visual-line-mode: t -*-

to the top of a file, and open that file in a new buffer, the line
wrapping does not work.  Checking `C-h m` tells me the minor mode
visual-line is enabled, but the lines in the buffer do not wrap as
expected.  If I then issue the command `(visual-line-mode t)`, then the
lines will wrap as expected. I see this behavior even when starting from
`emacs -Q`.

C-h v visual-line-mode:

  Use the command `visual-line-mode' to change this variable.

info emacs:
   48.2.4.1 Specifying File Variables
   
   To enable or disable a minor mode in a local variables list, use the
   `eval' keyword with a Lisp expression that runs the mode command (*note
   Minor Modes::). For example, the following local variables list enables
   Eldoc mode (*note Lisp Doc::) by calling `eldoc-mode' with no argument
   (calling it with an argument of 1 would do the same), and disables Font
   Lock mode (*note Font Lock::) by calling `font-lock-mode' with an
   argument of -1.
   
        ;; Local Variables:
        ;; eval: (eldoc-mode)
        ;; eval: (font-lock-mode -1)
        ;; End:
