Point out that total_cmp is no strict superset of partial comparison
Partial comparison and total_cmp are not equal. This helps preventing the mistake of creating float wrappers that base their Ord impl on total_cmp and their PartialOrd impl on the PartialOrd impl of the float type. PartialOrd and Ord are required to agree with each other.
