Logically in this moment the redo should be done by a negative
argument. But:

a
b
c

C-/ => Undo!

a
b


Now it should be possible to apply a redo.

M-- M-1 C-/ => Undo!

But the text did not change to

a
b
c
.

This would be good if it possible to implement it. I meant to see
in the minibuffer after applying an undo or a redo the text after
applying next an undo and the text after applying next a redo...
