path::extension() of parent directory #166

Open chan-lee opened 1 year ago

chan-lee commented 1 year ago

Describe the bug extension of a path ending in parent directory returns "."

To Reproduce CHECK(fs::path("/foo/..").extension() == ".");

Expected behavior but reference site is different ( https://en.cppreference.com/w/cpp/filesystem/path/extension ) CHECK(fs::path("/foo/..").extension() == "");

Additional context nothing

Yeah, you are right, that should not be.
