  I tried to play a little more with dir-locals and I see yet another
  limitation: it seems that there's no way to accumulate values across
  settings for different directories in the same tree.

  For example, I may create a class CLASS in my init file with some
  variable settings for it, and put "/usr/local/" in that
  class. However, since "/usr/local/src/emacs/emacs.git" has a
  .dir-locals.el file, my settings for "/usr/local" won't apply.

  Stefan, is there a chance to see my whitespace.el modifications
  applied eventually ?
