Dear GNU Developers,
Thank you very much for the project. It seems, if the low range number is higher by 1 than the high number, the program returns nothing (with exit code = 0), while 102-100 results in an error and 100-100 returns 100 as expected. For example, `shuf -i 101-100 -n 1` returns nothing with the exit code = 0 (unexpected). Expected (normal): `shuf -i 100-101 -n 1` returns either 100 or 101 with an exit code = 0. `shuf -i 100-100 -n 1` returns 100 with an exit code = 0. `shuf -i 102-100 -n 1` results in an error with an exit code = 1. Is that an expected behavior? Stay safe! Best and kind regards
