Ok, I will add the not operator, but rather than delegating to `or' it
seems simpler if it has a boy of its own like:

(defun TeX-shdex-not (arg)
  "NOT operator for style hook dialect expressions. The returned
value is a list of all dialects that are in
`TeX-style-hook-dialect-list' but ARG."
  (delq arg (copy-sequence TeX-style-hook-dialect-list)))

So not will be unary.
