I've been thinking about this. For it to look good there should be a
way to change the look of the summary line of a root when the subtree
under it is hidden (could be handy in general, if you want something
else then ...), to prevent something like this:

     Re: nnfolder/save problem...

I discovered that I could make the dummy line go away already (without
hacking gnus internals) by abusing gnus-summary-dummy-line-format (I
always wondered why you should have to end *-line-format in a "\n" in
the first place).

I have
 
(setq
   gnus-summary-make-false-root   'dummy
   gnus-summary-dummy-line-format " "
   ;; note tabulator at front
   gnus-summary-line-format
   "%1=%ua%U%R%4N %d %1{%[%z%}%* %2{%(%-20,20f%)%} %1{%]%2t %B%}%0{%S%}\n"
   )

which makes the dummy line disappear, leaving me with

     Re: nnfolder/save problem
        
But as said, that looks ugly when hiding threads, and the |--> makes
the thread look like it belongs to the previous one.

I'd be cool if you found the right way to do this.
