wrong separator in doc of QLoggingCategory

http://doc.qt.io/qt-5/qloggingcategory.html, section "Configuring Categories", subsection "Logging Rules" gives this example:
QT_LOGGING_RULES="*.debug=false;driver.usb.debug=true"

Besides QT_LOGGING_RULES, the subsection enumerates four other methods of setting the rules, among them setFilterRules(). The documentation of this function does not explain how to set multiple rules. Hence the user can do no better than extrapolate that the syntax of QT_LOGGING_RULES also holds for setFilterRules().

However, this is not the case. From the Qt5.9 source code it is clear, and experimentation confirms, that the separator in setFilterRules() must be a newline (\n), not a semicolon. This ought to be documented somewhere.
