Redo, as in the opposite of Undo, yes? (i.e. not as in repeat-complex-
command.)
There is redo functionality it just doesn't present itself as a
separate action. If you interrupt a series of undo operations with an
editing operation, you'll find that the behavior of undo changes: it
first undoes the interrupting edit, then undoes the undo operations
(i.e. "redo"). Once it's reached the end of the undo history, it
reverts to "normal" undo behavior. Give it a try. It's easier to
observe than explain.
I've gotten so used to it that I don't even notice it when I'm using
emacs anymore, though I confess I don't have as clear a mental model
of what's going on as I'd like -- at least not clear enough to be
able to draw a little ascii-art diagram. Might be a nice addition to
emacs info. Perhaps someone can explain the idea behind this behavior
to me in such a way that I can draw a picture.
