it depends ... we have none: no entry at all, knockout: some nil entry,
overprint: special entry
the thing is that when we have globally overprint on, we need s local
knockout :
\startoverprint
... \bgroup ...
\startknockout
...
\stopknockout
... \egroup ...
\stopoverprint
is nicer than
\startoverprint
... \bgroup ...
\stopoverprint
...
\startoverprint
... \egroup ...
\stopoverprint
