It would be nice if conf mode marked -keywords variables as safe to
set locally, so that e.g. one could add to ~/.nanorc

    # -*- mode: conf-space; conf-space-keywords: "set\\|unset" -*-

I believe the relevant change is simply to add

Is an arbitrary regexp "safe"? I imagine one could construct a
regexp/file combination that overflows the regexp matcher. Not too
serious, but perhaps it is best to leave this unmarked?

One can of course add such things at present, there is just a prompt
about applying them.

The worst that can do is cause a Lisp error.  We can consider it safe.
Please do add that property.
