Subject: [PATCH] gh formula fixes

- keep `head` spec to allow `--HEAD` installs from "prototype" git branch

- explicitly specify `version` because Homebrew failed to infer version
  number from `url`

- bring back bash/zsh completion support because the feature exists both
  in latest master and prototype, it just needs a newer tag

- add TODO block for future Linux release
