Rather, the 'test' binary and the 'lbracket' binary differ in one
crucial aspect: 'lbracket' requires its last argument in argv[] to be
"]".  It is not ksh, but lbracket itself that requires the matching ],
and it is this fact that allows us to obey POSIX while still allowing '[
--help' to produce help text, even though 'test --help' cannot do so
(that is, '[' has an escape hatch that 'test' does not).
