Subject: 24.3.50; coding system from .dir-locals.el doesn't work
Date: Thu, 29 Nov 2012 17:43:46 +0100

Specifying the coding system in a .dir-locals.el doesn't seem to have
the same effect as when adding a file local variable.  E.g.
I have this in .dir-locals.el:

  ((lisp-mode
    (coding . us-ascii-unix)))

and when opening a lisp file, C-h v buffer-file-coding-system shows
this:

  buffer-file-coding-system is a variable defined in `C source code'.
  Its value is undecided-unix

If I use a file local variable instead ;; -*- coding: us-ascii-unix -*-
C-h v buffer-file-coding-system shows this:

  buffer-file-coding-system is a variable defined in `C source code'.
  Its value is us-ascii-unix

This is the first time ever that I wanted to use directory local
variables.  So maybe I did something wrong.

You can't specify coding via dir-locals.

I've thought about it a few times, but it seems hard to make it work.

I think it would be worthwhile to make it work for the particular case
where it's not that hard, i.e. when the setting applies to all modes.
