This terse sentence needs to be explained in the rest of the doc
string, because, unlike "If non-nil", "When" does not explain itself.
The doc string should explain how to specify "when".  It should also
explain the different supported values.

Also, the default value is not one of the possible optional values.

Same comment to the other similar defcustoms where you changed a
boolean option to something else: their doc strings are now
obfuscated.

You assume here that "evaluated as root" explains itself?  I wouldn't
rely on that.

Thanks.
