I disagree.   No one has complained that we are being a "smartass" by
reporting this for "help" in psql:
You are using psql, the command-line interface to PostgreSQL.Type:  \copyright for distribution terms       \h for help
withSQL commands       \? for help with psql commands       \g or terminate with semicolon to execute query       \q to
quit

while to be really helpful we would display \?.  After extensive
discussion we chose against that because we wanted to steer people to
the proper commands, rather than have them consider 'help' as a valid
command.  The same is true for the MySQL commands --- we just want to
point people to the proper commands.
