So according to http://www.emacswiki.org/emacs/DirectoryVariables we can
set up lisp/.dir-locals.el like this:

     ((lisp-mode . ((indent-tabs-mode . t)
                    ;; would this work? whitespace.el is in Emacs...
                    ;; (whitespace-style (quote (trailing)))
                    (show-trailing-whitespace t))))

assuming we agree on the tabs.  Should we be explicit about anything
else?
