Emacs 21 doesn't look at the safe-local-variable property at all.  In
Emacs 21 there was the concept of risky-local-variable.  All variables
not marked as risky were considered safe (please CMIIW).  E.g. we had:
  (put 'mailcap-mime-data 'risky-local-variable t)
If `booleanp' is a problem in Emacs 21, `string-or-null-p' also would
be a problem.

Bye, Reiner.
