[emacs-support] support use of fci-mode
[emacs-support] support use of fci-mode

We used to force whitespace-mode on for everything in the Swift project
so people see their 80-column violations.  I personally like
https://www.emacswiki.org/emacs/FillColumnIndicator better, so I changed
things such that I could reverse the decision made by .dir-locals.el:

  (add-hook 'prog-mode-hook (lambda () (fci-mode t) (whitespace-mode -1)))
