Docs: Use Qt::SplitBehavior in preference to QString::SplitBehavior

The Qt version was added in 5.14 "for use as eventual replacement for
QString::SplitBehavior." Move another step closer to that goal.

Applied suitable wrapping round various char and string literals,
since docs are meant to show best practice.
