[issue27742] Random.seed(5, version=1) generates different values in PYthon2 and Python3

[Wolfgang Rohdewald]

New submission from Wolfgang Rohdewald:

The documentation promises backwards compatible seeders. I understand this as such that they generate the same random sequences. But for Python 2.7.12 and 3.5.2 this is not so, even if I pass an integer as seed value. The attached script returns different values.

Maybe I misunderstand the documentation - I believe it means that seed(version=1) uses the backwards compatible seeder, but it does not say so explicitly. If that is not so, the documentation does not say how to invoke the backwards compatible seeder.
