Much cleverer! But in this case there is a backward incompatibility
{doublesided,continue} = current {doublesided}
{doublesided} = would mean NONcontinuous
Actually whenever I wanted to use facing layout, I wanted NONcontinuous.
So I do not bother with this backward incompatibility. May be somebody
else do?
