Subject: [PATCH] Make the root symbol more telling in the DB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I spent a few minutes trying to understand why I had a field with an
empty symbol, until I realise that it’s because that was the symbol for
the root element.
Now that shouldn’t happen anymore
