ranges formatting doesn't work with format_to

[lethe555]

char buf[100];
	auto p = fmt::format_to(buf, "{}", std::vector<int> { 1, 2, 3 });
	*p = 0;
	std::cout << buf << "\n"; // output nothing
	p = fmt::format_to(buf, "{}", 1);
	*p = 0;
    std::cout << buf << "\n"; // output "1"

seems formatter<RangeT,Char>::format hasn't updated iterator out
out= format_to(out,...);

Fixed in 2e526a6. Thanks for reporting.
