If one is interested only in seeing the To header in the nnfolder
groups, then setting the nnmail-extra-headers variabel would be
counter-productive, since nnfolder doesn't do NOV headers.

Yes.

Almost.  It's used when receiving headers, whether they be HEAD
headers or NOV headers.

You have to use the %f spec to get to-or-newsgroup-or-from:

(setq gnus-summary-line-format
      "%U%R%z%I%(%[%4L: %-20,20f%]%) %s\n")

Adding this should be easy, but what should the score file syntax be?

For those who haven't followed the ChangeLogs, Gnus header vectors now
have an additional slot, which contains an alist of header/value
pairs.  This slot is called the "extra" slot.

To score on From we have

("from"
 ("Lars" -2000 nil s))

How about

("extra/keywords"
 ("gnus" 200 nil s))

That is, elements that are strings that begin with "extra" refer to
this slot, and the part after the slash refers to the header?

Or perhaps

("extra"
 ("keywords"
  ("gnus" 200 nil s))
 ("to"
  ("Lars" -200 nil s)))

I think this might actually be easier to do.
