Read "earlier iteration": it didn't get merged.

Nope, we add the refspec "foo", without the :destination part. The
remote end is unspecified (and defaults to "foo", but that is in the
transport layer).

It is impossible. We either:
- Get an explicit refspec from the user and never run
setup_default_push_refspecs() to begin with.
- Run setup_push_refspecs() and add *one* refspec depending on the
push.default value.
