IIUC, starting with Emacs 23.2, we can prin1 and read hash tables. If
that's correct, then `savehist-printable' could presumably be updated to
add this sexp to the cond: (hash-table-p value). IOW:
(defun savehist-printable (value)
"Return non-nil if VALUE is printable."
(cond
((stringp value))
((numberp value))
((symbolp value))
((hash-table-p value))
(t
(with-temp-buffer
(condition-case nil
(let ((print-readably t) (print-level nil))
(prin1 value (current-buffer))
(read (point-min-marker))
t)
(error nil))))))
