I think it makes sense to mark `default-directory' as safe.  If nobody
objects, I'll commit this change:

We could also use `file-directory-p' or `stringp' instead of
`string-or-null-p', but I think `string-or-null-p' is the best choice.

emacs-pretest is the wrong list for this.  I'll answer to this part on
auctex-devel (Cc-ing you).
