`feed.tmpl.xml` should be RSS2.0-conforming. Ideally each news item would have a date of publication, but RSS doesn't require it. I found it easier to copy `genblog.go` to `genfeed.go` than to shoehorn in feed logic to the blog generator. As such, `genfeed.go` might have some unnecessary stuff in it (though the go compiler didn't complain, so who knows?!). I also added the necessary machinery in `generate_homepage`. Of course, I did very minimal testing.
