Indeed, that would be even more useful, then you could just do
.joiner("\n") to get the original functionality.

However, I think Walter's goal here is to match the original wrap()
functionality.

Perhaps the prospective wrapped() function could be implemented in terms
of a byWrappedLines() function which does return a range of wrapped
lines.
