In fact we need that if we ever want to support reading from AT keyboards
and USB keyboards at the same time (we don't know which one is there, so
whenever using hardware access for one of them, we need to try both).

I was thinking that after terminal split is merged, we could either:

  - Turn the grub_cur_term_{input,output} pointers into lists, so that
    multiple terminals can be "current" at the same time.

  - Implement a "magic" input (or output) terminal that can be attached to
    other terminals and reads from (or writes to) more than one of them.
    The advantage of this is that the code doesn't have to be in kernel.

But I suppose we agree that the change I'm currently proposing is in the
right direction?
