I meant that for Lars, meaning that there's one central place where
topic names are assumed to be unique.  Sorry if I confused you, implying
you could edit it yourself.

I have played with gnus-topic-line-format a little and it should be
fairly easy:

;; set the format to use the function below (%i is indentation)
(setq gnus-topic-line-format "%i[ %u&topic-line; ] %v\n")

;; this function will return some string you can use, here it's just the topic name
(defun gnus-user-format-function-topic-line (dummy)
  name)

So you just need to write that function to return some transformation of
the actual topic name.  Then a topic like x.y.z could be transformed to
z or whatever you need.
