make line breaks in rss feed display?

Hi, I had an rss feed of a blog showing on my home page. However, when there was a long word, such as a long URL, there were no line breaks and it would break out of the sidebar and go across the page, which looked really bad, so I took out the feed. I’d like to have the feed. Is there any way to make line breaks (of course, I’d still want the links to work)? Maybe a widget that would contain the feed so it can’t “escape”? I’m in Thesis, if that matters. Thanks.
