I fully agree with David that we should not make such changes to the
behaviour of the display property that would break _the_ major package
actually using it for anything non-trivial.

Instead we can explicitly put an inivisible property together with the
display property on a priece of "hidden" text which should be ignored
by searches.  That need a little work to check all uses of display
properties, but it doesn't break any old code relying on the current

I don't know whether it actually works to put both invisible and
display on some text (with the effect of showing the image and
ignoring the under-laying text).  Would someone make some examples
to check it?
