When the first line of some substructure is visible and the rest of
that substructure is hidden, it seems to make sense to sort the
substructure with the first line.

However, if there are two substructures at the same level
and they are both invisible, it does not seem right for them
to stick together in sorting.

I have a feeling that sort-lines doesn't really make sense for an
outline, and other operations are needed for sorting in outlines.
But I am not sure of that.
