Up Vote if you want long urls to be chopped

I want any particularly long word to be forcefully split instead of making the page wider than the window. I'd have thought 200B is the "right" way to do this.

What I'd really like is markdown, but I don't suppose there are too many implementations of that sitting around for Arc.

long urls as in '<a href="http://link-to-site'" rel="nofollow">http://link-to-site'</a> in the discussion or 'story titles' in the main index?
