I do not think I can do that properly without your help :-(

The problem is that in lisp-mode.el:465 read is trying to read from
narrowed-region which does not contain an expression:

      (setq expr (read (current-buffer)))

How do I properly catch an error here and report it to user in the same way
read signals "End of file during parsing" error?

Can anyone help me with this?
