Steve, thank you.

The fig format is quite readable.

My version of the script came out longer:

BEGIN{done=0;started=0}
{ if ( started==1 && $0~/^ / ) { $0="#***GV BUG?*** " $0; done=1 } else {started=0}
  if ( done==0 && $0~/^2 3 / ) { $0="#***GV BUG?*** " $0; started=1 }
print }

I use BSD awk, perhaps gawk allows for
some simplifications.

Anyway, does it appear as a graphviz bug to you
that it adds image-size polygon when fig filter
is invoked?

Also, I was expecting Mrecord smooth box corners
to be translated to fig as arcs, but these appear
to be translated as open splines (3 4).
Is this intendend?

Many thanks

Anton
