There's some discussion around that in this thread:
https://www.postgresql.org/message-id/flat/9b4ea968-753f-4b5f-b46c-d7d3bf7c8f90%40manitou-mail.org
The key point is that \r in this case used to clear the "previous query"
buffer since there was nothing for it to remove from the "current query"
buffer. I argued then that that was confusing and counterproductive,
and I still think that.
