Sorry for the spam, it seems client specific (RSSOwl). I tried another client and it was fine, then looked at the RSS flux and it also looks fine.

I've been fooled by the fact that I only had the issue with HN but none of my many other feeds. My best guess is that you're using the HTML entity "&#x2F;" instead of the straight character "/" for URLs. Somehow RSSOwl handles this fine in <link> elements, but not in <comments>.

I'll submit the issue to RSSOwl.
