Whatever we do to automate this, I don't think we will ever
cover every possible hook that people would like to "accept
by default".

So I still propose that we provide a *simple* customization option
safe-local-eval-forms which is just a list that contains verbatim
copies of the eval hooks which the user considers as safe.

We could then enhance the functionality when the user is
asked to "eval local hook (y/n)" to "eval local hook (y/n/s)"
where "s" saves the hook in safe-local-eval-forms.

But just having the option would be great!
