@veky - Thank you for pointing out splitlines(keepends=True).  If we wanted consistency, then we'd change the sense and use something like .split(keepempty=True), however:

* I don't like run-on names, so I would suggest keep_empty
* Maybe just `keep` is enough
* Either way, this should be a keyword only argument
* The default would still be None (i.e. current behavior), but keep_empty=True would be equivalent to prune=False and keep_empty=False would be equivalent to prune=True in the previous discussion.
