Subject: Use origin/ref for all refs other than the system branch ref itself

The rationale here is that inside a checkout of a system branch, the
user should only be committing to the refs for that system branch,
because those are the only ones that 'morph merge' will look at.

This removes a problem where we could be confused by a ref with a
name that would be sorted before 'master' in the result of 'git
show-ref'.
