The change looks good, I had some easy to resolve comments.
Sadly, it seems that most of the changes are caused by the semantics change
of `print()` ... the scalashell code doesn't seem to be so much.
We certainly need to update the documentation as well. A lot of code
examples are doing print() and execute() together.
The docs should explain what print() is doing.
