initial scrambling of seed in do_setseed / RNG_Init
...init is called from set.seed, then
it receives the argument of set.seed after the initial scrambling.
If someone writes a user defined generator and wishes to get the original
seed specified in set.seed (which is my situation), then it may be useful
for him to know that the transformation
seed = 3602842457U * (seed - 2358491998U);
is the inverse to the initial scrambling. Hence, if it is applied to the
value received by user_unif_init, it provides the original value specified
by the user in set.seed.
Let me point out that the initial scrambling does not eliminate seed 0.
It only decreases the probabi...
