The focus for Nautilus' split view mode are occasional, temporary
switches to a split view mode for heavy-duty filebrowsing, not to
be a permanent double pane filemanager. Therefore, neither split-view
toggle status nor splitter position of a window are supposed to affect
subsequently opened windows. See comments at bug 608431.
