[O] Outline cycling does not preserve point's position

[Sebastien Vauban]

Hello,

Since a little while, I've observed that point's position is not anymore
preserved when cycling buffer's view with S-TAB.

Sometimes, point stays where it was (even when in the body of entries);
sometimes, not.

See http://screencast.com/t/1sr6Lezk:

- when on the first letter of "From", in that example, point's location is
  preserved;

- when on the second letter of it, point's location is lost: new position is
  at the end of the level 1 parent...

That's very annoying when you want to just look at your tree structure, but
don't expect to land somewhere else by doing so.

Best regards,
  Seb
