I see. In general the reason we need v:operator would then be that you
need it for situations where you need to get out of operator pending
mode, move around and restart the operator.
Did you copy the v:variable values because they change when executing
the other commands? A remark about that will be useful in the docs.
OK, I'll include the patch after sufficient testing.
