     -    bundle-uri: update bundle clone tests with new refspec path
     +    bundle-uri: copy all bundle references ino the refs/bundle space
     +
     +    When downloading bundles via the bundle-uri functionality, we only copy the
     +    references from refs/heads into the refs/bundle space. I'm not sure why this
     +    refspec is hardcoded to be so limited, but it makes the ref negotiation on
     +    the subsequent fetch suboptimal, since it won't use objects that are
     +    referenced outside of the current heads of the bundled repository.
     +
     +    This change to copy everything in refs/ in the bundle to refs/bundles/
     +    significantly helps the subsequent fetch, since nearly all the references
     +    are now included in the negotiation.
      
          The update to the bundle-uri unbundling refspec puts all the heads from a
          bundle file into refs/bundle/heads instead of directly into refs/bundle/ so
     -    the tests need to be updated to look in the new heirarchy.
     +    the tests also need to be updated to look in the new heirarchy.
