[O] Feature request: Numeric prefix argument for org-move-item-up/down

[N. Jackson]

It would be nice if org-move-item-up (and org-move-item-down) took
a numeric prefix argument to specify how many times to move the
item up (or down).

I was surprised that this is missing and I'm guessing there might
be a good reason for that? Otherwise, I think this would be a
useful addition.

Thanks,
N.
