I'd rather avoid hard-coding an upstream name here.  We do hard-code
‘origin’ as the default remote for ‘fetch’, ‘pull’, and ‘push’.  I'd
rather drop those in favor of the configured Git defaults (for
example, running a bare ‘git fetch’ if the user doesn't specify a
remote).  For most configurations, falling back to “Is ‘git show-ref
-s config’ a unique hash?” should be equivalent to hard-coding ‘git
show-ref -s origin/config’.

Cheers,
Trevor
