I can't rememeber.  I checked that it has been in v0.0.0 so it might
left over code from some experiments :-(.   ElGamal signatures are not
anymore used very much, but this should not been there - I'll better
throw a bug() here.

The code is out for nearly 2 years and nobody has noticed it - hmmm
...  Please go ahead and check more code.
