Yeah, it looks better with no arrowheads.  I think this version is
nicer:

(setq gnus-sum-thread-tree-leaf-with-other "├╮ ")
(setq gnus-sum-thread-tree-vertical "│")
(setq gnus-sum-thread-tree-single-leaf "╰─╮ ")
(setq gnus-sum-thread-tree-root nil)
(setq gnus-sum-thread-tree-single-indent nil)

I think it would look slightly better, if you could use a different
string when an article doesn't have children -- maybe like this:

But then you'd have to change the code.

No it still doesn't work.  When .gnus is loaded automatically I get this
value:

   gnus-sum-thread-tree-vertical's value is "\342\224\202"

But when I open it with `C-x C-f' and do `M-x eval-buffer' I get the
right value:

   gnus-sum-thread-tree-vertical's value is "│"

Hmm, when I loook at `gnus-read-init-file', the file is loaded like
this:

     (let ((coding-system-for-read
	    gnus-startup-file-coding-system))
       (load file nil t))

and `gnus-startup-file-coding-system' is bound to 'binary by default.
Doesn't that override the comment line?  When I bind
`gnus-startup-file-coding-system' to 'utf-8, it works.
