Inconsistency between fmt::to_string(_) and fmt::format("{}", _)

[avikivity]

#include <fmt/format.h>
#include <iostream>
#include <vector>
#include <fmt/ranges.h>

int main() {
    std::vector<std::string> x = { "abc", "def"};

    std::cout << fmt::format("{}", std::string("abc")) << std::endl;
    std::cout << fmt::format("{}", x) << std::endl;
    std::cout << fmt::to_string(x) << std::endl;
    return 0;
}

prints

abc
["abc", "def"]
[abc, def]

to_string() and fmt::format() return different results. I understood to_string() to be a simpler/faster fmt::format() with everything defaulted.

Why does the range formatter insert unnecessary escapes? Maybe it would be better to only insert them to make the output unambiguous.

Fixed in 19276d7, thanks for reporting. Conditional escaping is an interesting idea but it might be confusing to users and the format is pretty much fixed anyway.
