you can comment this in cont-new.mkiv

% \def\pagedir{\expandafter\gobblethreearguments}
% \def\bodydir{\expandafter\gobblethreearguments}

i'm trying to figure out what dirs make sense (even when all are enabled 
the alignment is no 100% ok; for instance, why should bodydir influence 
textdir and pardir (i.e. when i would expect the content to be rl 
independent of page/bodydir

(we need some higher level interface and not these low level *dir commands)

best is if you and idris sort this out (is part of idris onthology)
