With an invalid arc configuration

  $ hg log -T '{syncstatus}\n' -r .
  arcconfig configuration problem. No diff information can be provided.
  Error info: no .arcconfig found

  $ echo '{}' > .arcrc
  $ echo '{"config" : {"default" : "https://a.com/api"}, "hosts" : {"https://a.com/api/" : { "user" : "testuser", "cert" : "garbage_cert"}}}' > .arcconfig

And now with bad responses:

And finally, the success case
