现实git分支

Parses out the branch name from .git/HEAD:

find_git_branch () {
  local dir=. head
  until [ "$dir" -ef / ]; do
    if [ -f "$dir/.git/HEAD" ]; then
      head=$(< "$dir/.git/HEAD")
      if [[ $head = ref:\ refs/heads/* ]]; then
        git_branch=" → ${head#*/*/}"
      elif [[ $head != '' ]]; then
        git_branch=" → (detached)"
      else
        git_branch=" → (unknow)"
      fi
      return
    fi
    dir="../$dir"
  done
  git_branch=''
}
