I'm having big problems in reading emails and news posts in gnus in that
everything is showing with *all* of their headings, like this one -

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

I've looked back through the archives from this year but can't find a
solution. So, how do I get it just to have normal, sensible headers like
"From, Subject, To, Date" please?

Thanks
Sharon.
