I'm not sure when it was added. It may be missing from other platforms as well. This currently doesn't handle the string manipulation options (-f, -s and -w in MinGW anyway), since there is currently no need for it. Since xrange defaults to starting at 0 instead of 1, and treats the end as exclusive instead of inclusive, the args need to be extracted instead of doing: xrange(*[int(a) for a in sys.argv[1:]]) Therefore, the step might as well be added, even though there is no current use.
