Hmm. I've a patch at home at ensures that overviews are fetched in the group
fetchmode when in online mode, so that (for example) if the group is marked
FULL then all articles will be downloaded when you --fetch after an online
session - something that doesn't happen at the moment.

This is nearly what you want when a group is THREAD, but not quite (I think).
Currently THREAD is done by seeing checking each article's References: when its
overview is loaded, and marking the article for retrieval if it has a reference
we think 'interesting' (i.e. a referenced article has been read or tried to be
read).

But when online this won't work quite as you want, as only articles new at the
next fetch which reference the read article will be read in full. So, to take
your example, article 3 wouldn't be read at the next fetch.

In fact, thinking about it, marking article 1 as to be read is easy. But
marking article 3 is hard; currently you'd need to scan every article in the
overview database to see if it references article 2.

So I think I'll put in the change for using the group fetchmode when online,
but that will have to do.
