I think the next big question is if/where we want to document this new
behavior. We don't mention 'help' in the psql manual page, but we do
display it in the startup banner:

$ psql test
psql (11devel)
--> Type "help" for help.

What do we want to do with 'exit' and 'quit'? Just leave them
undocumented as compatibility commands? If so, I should at least add a
C comment about this.
