Sigh we really messed up seq in that release :(
The attached should fix it:

I also notice another regression,
which I'll fix in a moment.

 $ seq 0 1 0
 0
 1

thanks,
Pádraig.

Dear all,

There is another bug that sneaked into the speed patch of seq on 13.09.12:

560   if (all_digits_p (argv[optind])
561       && (n_args == 1 || all_digits_p (argv[optind + 1]))
562       && (n_args < 3 || STREQ ("1", argv[optind + 2]))
563       && !equal_width && !format_str && strlen (separator) == 1)

That should probably be:
560   if (all_digits_p (argv[optind])
561       && (n_args == 1 || all_digits_p (argv[optind + 1]))
562       && (n_args < 3 || STREQ ("1", argv[optind + 1]))
563       && !equal_width && !format_str && strlen (separator) == 1)

Best regards,
 Marcel
