Dear list, It seems as if the pre_output_filter only gives you the nodes in the body block but without the \headline and \footline. I would have expected that those are included because \plainoutput performs
\shipout\vbox{\makeheadline\pagebody\makefootline}
and I would have expected to get the vlist defined by the above \vbox
inside the callback. Am I doing it wrong or am I using the wrong callback?
Cheers, Henri
