Sure, it does not win the "portable to Version 7" price, but our
scripts don't do that, anyway.

I agree we do not give the "portable to version 7" prize
anymore.  But you made me realize another thing.

I think it should make sure orig_namespace has one and only one
trailing slash, because otherwise "--original refs/heads//"
would lead you to the same disaster.
