texinfo-insert-menu

texinfo-insert-menu is a compiled Lisp function in `texnfo-upd.el'.

(texinfo-insert-menu MENU-LIST NODE-NAME)

Insert formatted menu at point.
Indents the first line of descriptions, if any, to the value of
texinfo-column-for-description. Indenting leaves trailing whitespace
in a menu that lacks descriptions, so descriptions will format well.
In general, a menu should contain descriptions, because node names and
section titles are often too short to explain a node well.

MENU-LIST has form:

(("node-name1" . "description")
("node-name2" . "description") ... )

However, the description field might be nil.

Also, the node-name field might itself be a dotted pair (call it P) of
strings instead of just a string. In that case, the car of P
is the menu entry name, and the cdr of P is the node name.
