This was three years ago, and from what I can tell, nobody has changed
sort-lines to be aware of invisible lines...  I can see the case for
allowing the caller to control this, but none of the patches proposed
look acceptable to me (for instance, one made sort.el check for outline
mode explicitly, which seems backwards).
