This is at least "controversial."  Sorts treat -0 and 0 as equal, but
they have to be recognized as different for various purposes such
as getting the directions right for functions of complex variables.
So, it seems clear to me that the "right" result for the first line
above is:  [-3:-0] -> [-3 -2 -1 -0].

I cannot think of an argument for not doing this.
