Cleanup comments in .emacs

visual-line vs word-wrap:

AFAICT, visual-line is word-wrap plus some customizable options:
- fringe indicators;
- specialized editing commands.

So there is no reason to bother with word-wrap.

Appending through dir-locals:

I  wanted to  have lists  in dir-locals  *appended* to  the variables,
rather than overwritten, eg:

    ;; in .emacs:
    (setq my/foo '(1 2 3))
    ;; in .dir-locals.el:
    ((c-mode . ((my/foo . (4 5 6)))))
    ;; M-: my/foo in a C buffer:
    (1 2 3 4 5 6)

I  don't think  there  is  built-in support  for  this.   I guess  the
simplest way to emulate it would be to

1. put (4 5 6) in some other variable my/bar;
2. write a hook that appends my/bar to my/foo.
