A) In case it wasn't clear, I am not a Emacs hacker, I am a GTK+ hacker
B) It would be a mistake that assume that anything I say about emacs
is informed by more than (many thousands of hours of) casual
end user use plus theoretical considerations.
C) My main point was that the effect of invisible text on locating the
end scroll position of the buffer should be roughly the same as
the effect of it on computing the correct scrollbar size.
Stefan Monnier seemed to think that invisible text would make
computing the end scroll position of the scrollbar very hard.
That implied to me that Emacs computed scrollbars based on total
characters not visible characters; but I didn't research the
point.
