Edit: Sorry, I forgot that I had patched my local bundle. This might indeed be an oversight, I'm looking at it now.

Edit 2: This is being fixed now[1]. Everything below is stale.

I couldn't reproduce this:

  % which git
    /opt/homebrew/bin/git
  % git ls-remote https://git-emudhra.we-have-a-problem.com/check.git
    fatal: unable to access 'https://git-emudhra.we-have-a-problem.com/check.git/': SSL certificate problem: unable to get local issuer certificate

Make sure your `git` binary is Homebrew's, not the system/XCode CLT one. If you see `/usr/bin/git`, you're not using the Homebrewed Git.
