The way to specify that a variable is safe for certain categories of
values is by giving it a `safe-local-variable' property. For example:
(put 'foobar 'safe-local-variable 'booleanp)
But what is the recommended way of doing this with a variable that is
defined in the C sources? One possibility is to put the above form
somewhere in a Lisp file that is preloaded, like simple.el. Is there
a better way?
TIA

This is currently done ~ line 2770 of files.el.

Thanks, this is exactly what I was looking for.

You can also call Fput in an equivalent way from C, but it's usually
a lot more convenient to do it from Elisp. I guess we could even
retarget the cus-start.el to be used specifically for these kinds of
uses where we stash Elisp that conceptually is related to the C code,
but just happens to be a lot more convenient do in Elisp.
