Hi ZheNing,
Thanks for picking up the issue. It's good to see that the GGG issue
tracker is helpful.

Hmm, others may disagree but I don't really like the idea of
`--previous-count`. It may be useful for populating "Range-diff vs <n>"
instead of just "Range-diff" but I don't think it's worth the cost of
maintaining this option.

I would just remove this hunk entirely and keep the existing logic...

...then over here, we can do something like
const char *reroll_count = NULL;
int reroll_count_int = -1;
and then...

...over here we can use Junio's integer parsing example and assign
reroll_count_int only if reroll_count can be parsed into an integer.
