This is a bug (most probably in luatex) which I've meanwhile reported
to the texinfo team.  Maybe they can fix it easily with a modification
of `texinfo.tex' – a long-term fix in luatex doesn't help us right
now.

Until then, we might replace `§' and `¶' (the latter character also
fails with luatex), with the commands address@hidden' and address@hidden', 
respectively.
Patch appended.
