   Could you be more precise?  What would the behavior of
   intangible text be, as you recommend?

I was only talking about invisible-intangible, although I believe that
it might be good to take a look at visible-intangible too (I will do
that in a later posting).

         I believe that Stefan's implementation
       and the invisible-intangible feature are pretty similar except for
       their treatment of stickiness as to which side point is going to move.

   What is the difference in behavior, precisely?

I originally misunderstood the difference in behavior, mistakenly
thinking that it had something to do with stickiness.  Apparently, the
only difference is that Stefan's implementation only adjusts point
after an interactive command, whereas the alternative parallel
implementation adjusts it inside non-interactive code as well.  As the
entire motivation for the feature is to prevent the cursor from
appearing to stand still in interactive use, I definitely believe that
Stefan's version makes more sense.  It also gets rid of Klaus' bug
without need for any other change in code.

Sincerely,

Luc.
