 I think the issue is which fields are ''in'' the `r` line.  The `r` line
 is wrong in arma's first example because it has a microdescriptor hash
 instead of a descriptor hash.  It looks like a ns-flavored `r` line but
 the descriptor digest wrong, rather than being omitted as in the md-
 flavored consensus.  Somehow this seems to be confusing pytorctl.  I think
 one thing arma was wondering about is how stem handles this.
