bah, probably i ran some test .. some code there only works in older 
luametatex .. (keep in mind that i seldom run these manuals as a whole 
so sometimes the tex file are newer than the pdf document) .. esp the 
history documnents are sensitive for experimental features that evolve 
(i had to comment the fences chapter because we now have neater mechanism)

i pushed an update (hopefully better; you shoulkd be able to process the 
files but math exmaples might not what is discussed due to the updates 
we did)

as you're in update mode, here is something to play with .. i bet you 
can figure it out without documentation (and if you have input on this 
for us ... you're welcome)

Hans
