I probably wouldn't spend a ton of time worrying about this personally.
Without additional information, I think it's impossible for us to
determine a-priori whether or not a file underneath $GIT_DIR should be
interpreted as a pseudo-ref or not.

I agree with your reasoning that since this is opt-in via a new
command-line flag, that we're probably OK here enumerating the files in
$GIT_DIR, and printing out the ones that look like pseudo-refs.

Thanks,
