Thanks, Barry, useful.
Guenter, by "I don't know" I mean I don't know which account of it is right. You, apparently, do know. This might be omniscience on your part, or it might be jumping to conclusions too early.
I am sceptical of the account you quoted, for the reasons I gave, and Barry's post suggests scepticism is in order.
Why this makes me the master of demagogy and what have you, I'm not sure. But have it your way.
