cpuset(1) ranges doesn't work as expected

Hi,

I want to believe that cpuset(1) was okay when doing range selection for CPUs using the - character. Now I think it doesn't act as expected, instead it works similar to what a comma would do. Anyone noticed this also?

Code: 
root@freebsd:~ # cpuset -l 0-2 nproc
3
root@freebsd:~ # cpuset -l 0,1,2 nproc
3
