Yes, this patch is wrong.  Looking through the archives, it seems to
have been meant to address the problem at

  http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg00945.html

However, looking at that recipe, it seems the problem is actually
handled by my 2009-01-10 (it_method == GET_FROM_DISPLAY_VECTOR) change
instead.  So either my 2008-01-26 change was bogus all along, or some
other change in the meantime made it bogus.

I've reverted it in the branch; thanks for investigating.
