It's pretty straight-forward:

(setq gnus-summary-line-format "%U%R%z %B%-23,23n %s\n")
(setq gnus-sum-thread-tree-root "")
(setq gnus-sum-thread-tree-single-indent "")
(setq gnus-sum-thread-tree-leaf-with-other "├╮ ")
(setq gnus-sum-thread-tree-vertical "│")
(setq gnus-sum-thread-tree-single-leaf "╰─╮ ")

It's a pitty we can't assume that everyone has a unicode font, so we
could make some attractive defaults in Gnus.  

Hmm, the tree display could probably also be made to look a lot prettier
than today with some box-drawing glyphs.
