* Empty strings are now direct constructed as `std::string()`, not as empty string literals. * `startsWith` and `endsWith` no longer construct new a string. This should be an improvement for libstdc++ when using older standards, as it doesn't use SSO but COW and thus even short strings are expensive to first create. * Various places now use char literal instead of string literals containing single char. ** `startsWith` and `endsWith` now also have overload that takes single char. Generally the performance improvements under VS2015 are small, as going from short string to char is mostly meaningless because of SSO (Catch doesn't push string handling that hard) and previous commit removed most string handling if tests pass, which is the expect case.
