#538 c++20 three way (spaceship) operator

[neok-m4700]

On latest trunk [672]:

a.hh

struct Int
{
    int i;
    auto operator<=>(const Int& rhs) const = default;
};

$ astyle --pad-oper a.hh

struct Int
{
    int i;
    auto operator<= > (const Int& rhs) const = default;
};

The operator <=> should not be changed.
