Hi Richard and Stefan,

Our discussion a long while ago seems to converge to making nil safe for
auto-fill-function. I have been using

  (put 'auto-fill-function 'safe-local-variable 'null)

in my .emacs, which enables users to disable auto-fill on a per-file
basis. May it be possible to make that default in Emacs?


Best wishes,
