    Revert "screen: Use clean env when creating new tab"
    
    The patch is correct, but it exposes a deficiency in the desktop
    environment in that the WM/shell's environment contains necessary
    env vars (e.g. ssh-agent variables) that are missing from the
    systemd --user / d-bus activation environment.  The desktop will
    need to update the activation environment, but until that is done,
    reverting the patch will revert gnome-terminal to the previous
    behaviour of effectively using the environment of the client
    of the first terminal created for all new terminals opened via
    new terminal/tab/window.
    
    This reverts commit 9bb94e3aab84ecc4e7733d0ee001ee50256bd273.
