I think it should either skip it properly, or not at all.  There is an
inconsistency here between parts of isearch.  C-s C-w also produces
these error messages, and the "[end of node]" is just wierd, from a
user's point of view.

I think this should be fixed, somehow, for Emacs 24.3.  I would agree
with your suggestion that isearch should simply yank the invisible text.
