QKeySequence::toString documentation not entirely correct

On http://doc.qt.io/qt-5/qkeysequence.html#toString there is noted that:
On OS X, the string returned resembles the sequence that is shown in the menu bar.

That's only true if the non-default parameter `QKeySequence::NativeText` will be used, by default `QKeySequence::PortableText` is used which shows the `Command` key as `Ctrl`.
