Re: [PATCH v2] t1401: check symbolic-ref exit codes and --quiet silence

I would favor continuing to not test for the exact error code, and would rather not disturb anything scripts may already rely on.

In either case the git-symbolic-ref.adoc NOTES are out of sync with the actual behavior:

  'git symbolic-ref' will exit with status 0 [...], with status 1 if the
  requested name is not a symbolic ref, or 128 if another error occurs.

To describe the actual behavior:

  'git symbolic-ref' will exit with status 0 if the contents of the
  symbolic ref were printed correctly, with status 1 if the requested
  name is not a symbolic ref and --quiet was given, or with status 128
  if it is not a symbolic ref and --quiet was not given, or another
  error occurs.

If that sounds OK I can update the adoc and call it good.

Thanks, Nikolaus
