Thanks; this is incredibly helpful!

I've started a branch to do a test case to demonstrate all these bugs
; it's called "ed25519_keygen" in my public repository.  It also adds
a couple more features to '--keygen'.  It does cases 2...4 so far; I
want to make it cover 5..10.

Once I've got it demonstrating all the cases, I'll try to clean it up
and start hammering down the bugs.

best wishes,
