Comment(by was):
I fixed this one line in your patch (which was wrong, and simply reposted
it with the line fixed):
{{{
# we have h(D*f^2) >= (1/c)*h(D)*phi_D(f) >=
h(D)*euler_phi(f), where
}}}
changed to
{{{
# we have h(D*f^2) >= (1/c)*h(D)*phi_D(f) >= (1/c)*
h(D)*euler_phi(f), where
}}}
With this change, I'm happy with your patch, so I think you can set it to
positive review.
