Hi, Taco:
In TeX's Packaging algorithm, TeX wraps lists into boxes. Knuth create
two functions, hpack (p,w,m) and vpack (p,w,m)=
vpackage(p,w,m,max_dimen) to solve this problem.
In the LuaTeX manual, (4.1.3.13), only node.hpack is given. maybe we
should also write something called node.vpack?
I wrote one for LuaTeX since I need it in my document project. I think
it will be useful to others too. The code is easy to write by
following yours and here is the patch:
fyi: vpack is on the agenda for later (probably after the complete
rewrite to cweb)
quite certainly vpack will demand a rewrite of core code as it has to
deal with quite some related things as well
it's no problem of course to use your variant locally for a while, but
be prepared for a different interface
