Hrrm, it's a bit more complex than that.  Again, with a pgp5 key that
only knows cast5:
gpg: DBG: mask=0000000000000000000000000000000000000000000000000000000000000008
gpg: DBG: prefs of type 1: selected -1

I think the initial seeding of 'bits' will have to allow for all the
algorithms GPG knows, not just 3DES.
