    Outline-mode has a problem that I would like to fix.  To see the
    problem, hide an entry (C-c C-c) in an outline-mode buffer, and put
    point at the end of the heading with C-e.  Point will then be located
    to the right of the ellipsis, and as far as emacs knows, point is on
    the last line of the hidden entry.  Typing characters or hitting
    backspace, and many other commands will affect the last line of the

This is true, and it is consistent.  If you type C-e on the heading
and move past the ellipsis, you go just before the newline at the end
of the entry.  If you insert text there, it appears to be, and is,
located before that newline.

    When an entry is collapsed in outline-mode, what actually gets marked
    invisible is everything from the newline of the heading to the
    character before the final newline of the entry.  It would make more
    sense, if the newline of the heading were left visible, and the final
    newline of the entry were hidden.

I think the reason for this is that the newline that is displayed
appears to be right before the next entry.  If the newline character
that corresponds to is NOT the one right before the next entry,
you get strange results.
