I like keeping the range/multirange operators together since they are
so similar for both types, but if others disagree I'd be grateful for
more feedback.
You're right that I left in a few references to the old @+ style
operators in the examples; I've fixed those.

Okay. I think a new 'm' value is warranted because they are not interchangeable.

I've added a comment about this. I put it at the top of DefineRange
but let me know if that's the wrong place.
The attached file is also rebased on currrent master.
Thanks!
