    I think my recollection is wrong.  The only case where it could happen is
    if the buffer was modified (in which case we have to be more careful
    because we can't really know what was the original position before the
    command), or if the buffer has some intangible properties or other
    point-motion hooks in which case many different things can happen.

That is good.

With your code, is it possible for point to be either before or after
the invisible text?  If so, how do you prevent those from being two
point values which would appear at the same screen position?
