Patch looks good, thanks.
One small comment, though.

Shouldn't you check errno here, like:
char *arge;
errno = 0;
intmax_t arg = POS==3 ? 0 : strtoimax (f, &arge, 10);
if (errno == 0 && 0 < arg && arg <= INT_MAX && *arge == '$')
[...]
I think that would handle all bad cases.
For example, I think "%$" might return 0 but set errno to EINVAL.
