Yes.  I'm planning to fix this (this is a Gnus limitation), but I have a
a few too many work in progress projects at the moment.
The second feed is an RSS feed.

Honestly, your code is much more beautiful than the code it replaces.

I think your arguments make sense, and you solved the issue in a way I
didn't consider (and is much simpler than what I had in mind).
I'll install this change (probably add a comment explaining the
rationale too, since I was hard to convince) when I get home.

Thanks,
Daniel
