If you have wide lines containing a lot of content, increasing the line spacing (or, leading) can help somewhat in readability. Unfortunately, terminals and editors don't always make this easy. Certainly not as easy as changing their display width. You burn some vertical room -- all the more apparent with today's widescreen trend. But when you're trying to keep the strain from driving you crazy when reading a bunch of adjacent wide lines, it can help. Also, other visual differentiators. Remember the old, wide band-printer reports, done on paper that varied background color every 5 lines or similar?
