The documentation is describing the API for both the QString v1 and v2
APIs.

The way to get the correct signature for any method is to use help()...

    help(QValidator.validate)

The generated docstrings will be correct (for the default QString API).
Changing the documentation so that it is driven from the same information
is on the TODO list.
