In the Magit manual I usually use separate nodes for sections and
subsections, but in a few cases a section's children should be part
of the section's node.

I accomplished that by adding an additional element property NONODE
and redefining `org-texinfo-headline' and `org-texinfo--menu-entries'
accordingly.  Here is an equivalent patch:

The property should probably be renamed to e.g. NOCHILDNODES, since it
is the *children* of the section which has this option set that do not
get any nodes of their own, not the section for which the property is

Please consider adding this or something similar.  Thanks!
