Yes, that's kinda ugly.

Yup, the following:
diff --git a/lisp/info.el b/lisp/info.el
index 3203c5f171..abef57f79f 100644
--- a/lisp/info.el
+++ b/lisp/info.el

(let ((section "Top"))
(while nodes
(let ((node (assoc (car nodes) node-list)))
- (unless (member (nth 2 node) (list nil section))
- (insert (setq section (nth 2 node)) "\n"))
(insert (make-string level ?\t))
(insert "*Note " (car nodes) ":: \n")
(Info-toc-insert (nth 3 node) node-list (1+ level) curr-file)
makes the TOC much nicer. As a test case, open the ert info file and
hit `T'.
Does anybody know what the reasoning behind adding these seemingly
doubled lines is?
