You are right.
this means that I cannot really set bug-reference-url-format in the
"Local Variables:"
section together with "mode: bug-reference" if I also set
enable-local-variables to :safe.
if I set it to "t", I get asked about local variable for _every_ file
operation (including diff!)
in the emacs tree and anything else ignores my local settings of
bug-reference-url-format.

For your reference, I set bug-reference-url-format to
clisp-bug-reference-url-format:

(defun clisp-bug-reference-url-format ()
 (concat "http://sourceforge.net/tracker/index.php?func=detail&aid="
         (match-string-no-properties 2)
         "&group_id=1355&atid="
         (let ((kind (match-string-no-properties 1)))
           (cond ((string-match "[Bb]ug" kind) "101355")
                 ((string-match "[Pp]atch" kind) "301355")
                 ((string-match "RFE" kind) "351355")
                 (t (error "unknown bug kind [%s]" kind))))))

I expect this kind of setting to be fairly common unless one is using
the gnu bug tracker or something similar.

the bottom line is that there _must_ be a way to use something
reasonably flexible here and still not be asked "local variable"
