Constructors are provided that store zero, one, or two paths associated with
an error.

const path& path1() const noexcept;
Returns: A reference to the copy of p1 stored by the
constructor, or, if none, an empty path.
const path& path2() const noexcept;
Returns: A reference to the copy of p2 stored by the
constructor, or, if none, an empty path.
const char* what() const noexcept override;
Returns: A string containing runtime_error::what(). The exact format is unspecified.
Implementations are encouraged but not required to include path1.native_string()
if not empty, path2.native_string() if not empty, and system_error::what() strings in the returned
string.
