FormatError when formatting empty std::string_view

[dermojo]

When trying to format an empty string_view, fmtlib raises a FormatError because the contained pointer is nullptr. Minimal example:

#include <string_view>
#include <fmt/format.h>

int main()
{
  std::string_view x;
  fmt::print("{}\n", x);
  return 0;
}

I'd expect an empty string to be printed.

Good catch, thanks! Fixed in 8c29459.
