print problems

[RobinHankin]

In print.Rd we see:

a <- rmvp(4)
a
print(a)
print(a,stars=TRUE)
print(a,varorder=rev(letters))

But the last two lines do not work and give the same result as print(a):

  a <- rmvp(4)
>      a
mvp object algebraically equal to
4 a^7 d e^4 f^11 + 3 a^15 b^2 d^6 + 2 c^6 f^11 + c^7 e^7 f^7
>      print(a)
mvp object algebraically equal to
4 a^7 d e^4 f^11 + 3 a^15 b^2 d^6 + 2 c^6 f^11 + c^7 e^7 f^7
>      print(a,stars=TRUE)
mvp object algebraically equal to
4 a^7 d e^4 f^11 + 3 a^15 b^2 d^6 + 2 c^6 f^11 + c^7 e^7 f^7
>      print(a,varorder=rev(letters))
mvp object algebraically equal to
4 a^7 d e^4 f^11 + 3 a^15 b^2 d^6 + 2 c^6 f^11 + c^7 e^7 f^7
