That would be my fault.  I re-instated option processing for the server
after it had been accidentally deleted, but did it too simplistically.

That will affect hugs too, which is probably not a good thing.  I've
put the old code back -- it affects runhugs run either way and also
ffihugs, which is too much, but at least not hugs.
