[luatex] post_linebreak_filter (partly) broken?

Hi Hans et al

one last one before midnight:

post_linebreak_filter like pre_linbebreak_filter both receive two arguments


while one can query groupcode in pre_linebreak_filter it is always 
"empty" in post_linebreak_filter regardless of what it was in pre_...

My guess is that  this is again a single global variable that is being 
reused in several places (ie the hpack_filter ???) so that it gets 
clobbered depending on what linebreak does

again not urgent as one can store the correct value in pre_... in a 
private global variable ...

but fixing the housekeeping would be nice here

good night
