It's possible of course, I haven't looked at how it's written, but I find
it unlikely. The most obvious way to implement it doesn't need to look at
the undo elements.

The command is called `undo-only' and I had originally bound it to
C-x U (i.e. a stronger version of C-x u since it skips over matching
undo-redo pairs in the undo-list), but Richard reminded me that we do
not like to bind different commands to uppercase and lowercase commands and
I haven't bothered to try and find another binding for it.

C-f C-/ C-/ C-/ ...
Maybe we should arrange that calling `undo' after `undo-only' does not
continue undoing but switches to redo instead, so that redo.el would amount
to (defalias 'redo-undo 'undo-only) (defalias 'redo-redo 'undo).

I find redo.el to remove functionality rather than to provide it.
But I did go through the trouble to implement undo-only.
