Comment:
the attached patch does several things:
1) it fixes two typos in {{{gen.pyx}}}
2) it corrects the behaviour of {{{pari(n).isprime(1)}}} which incorrectly
was returning {{{False}}} for prime n
3) for prime n, now {{{pari(n).isprime(1)}}} returns a tuple {{{(True,
cert)}}} where {{{cert}}} is the primality certificate (currently as Pari
object, I didn't figure out how to convert it to a Python object)
Comments are welcome.
