+++ This bug was initially created as a clone of Bug https://bugzilla.redhat.com/show_bug.cgi?id=841065 +++

Description of problem:
man moduli says:
 4     Sophie Germain; (p+1)*2 is also prime.
but, (p+1)*2 is obviously NOT a prime.
It should be p*2+1.

oops. It seems we fixed this upstream about a year ago but didn't get the manpage fix into portable OpenSSH. I've merged it and it will be included in openssh-6.2.
