FYI, this was mentioned in the PG 11 release notes:

       <para>
        Allow <command>quit</command> and <command>exit</command> to
        exit <application>psql</application> when given with no prior input
        (Bruce Momjian)
       </para>

       <para>
        Also print hints about how to exit when <command>quit</command> and
        <command>exit</command> are used alone on a line while the input
        buffer is not empty.  Add a similar hint for <command>help</command>.
       </para>
      </listitem>
