Sorry, I have no clue.  I use `gnus-fetch-old-headers' set to 'some and
no special parameters like `(display . all)', and when there are two new
messages in the same thread, then everything up to their common parent
is shown (as advertised by the value 'some).  So maybe you want to try
that just to see if the `display' parameter has something to do with
that.

Ah, ok, now I understand.  So I've put %k in my
`gnus-summary-line-format' as well, and my numbers are all ok even after
I pulled in more articles via `A r'.  So what does that tell us?  I
don't know. :-(
