Agreed. The shortest unambiguous match shall be  sufficient.  On  the
other  hand  we  should  allow for longer subcopmmand names, or we'll
very soon see artifical command identifiers that nobody can  remember
well  because  they  were  artificially  chosen to use a still unused
letter.

Best regards,
