I would think it's the opposite. Long lines look _horrible_ without
"-S", as they get wrapped at awkward points. Using "-S" means that long
lines don't bug you, unless you really want to scroll over and see the
content.
I really think the right solution here is to teach less to make it more
obvious that there is something worth scrolling over to. Here's a very
rough patch for less, if you want to see what I'm thinking of.
