The printf zero-padding should be a built-in feature, as dealing with lots of filename structures and date structures needs zero-padding.
I often end up doing things like "for i in $(seq -w 1 100); do.." in bash.
My preference would actually be that -r does automatic zero-padding to fit the widest number that will come out of the range, and another variant like -R would suppress that behavior; but it could also be an optional switch.
It might also be nice to have the code recognize when start is greater than end, like -r 10 1, and support backwards-counting.
