Perhaps something like:
	+
	`<n>` can be any string, such as `-v1.1`.  In the case where it
	is a non-integral value, the "Range-diff" and "Interdiff"
	headers will not include the previous version.

I don't think it's necessary to do this at all. We can just leave `reroll_count < 0` here.

Others may disagree but I'm okay with leaving this as "Nth re-roll". It's just a synopsis. More information can be found in the docs.

This 0 < reroll_count check is unnecessary; it was initialised to -1 and it hasn't changed since here.

Also, we can take advantage of the strtol_i() function, which can perform bounds checking and error checking for us. This allows us to assign reroll_count only when a valid integer is found so we can eliminate previous_count_string().

Something like:
	strtol_i(reroll_count_string, 10, &reroll_count);
