271 if the fitCursor call refers to some point in never-explored-land, then we
272 don't have y information in insets there, then we cannot even do an update
273 to get it (because we need the y infomation for setting top_y first). So
274 this is solved in put_selection_at with:
276 - setting top_y to the y of the outerPar (that has good info)
278 - calling cursor().updatePos()
279 - then call fitCursor()
