With Zsh, I am using:

    # Expand ... to ../..
    function vbe-expand-dot-to-parent-directory-path() {
      case $LBUFFER in
        (./..|* ./..) LBUFFER+='.' ;; # In Go: "go list ./..."
        (..|*[ /=]..) LBUFFER+='/..' ;;
        (*) LBUFFER+='.' ;;
      esac
    }
    zle -N vbe-expand-dot-to-parent-directory-path
    bindkey "." vbe-expand-dot-to-parent-directory-path
    bindkey -M isearch "." self-insert
