cal: simplify leap year rule
Gregorian rule for leap years has been adopted by reformation in year
1782 (Calendar Act 1750), but all tools (date, SQL servers, etc. etc.)
don't care about it and apply the new rule for all year -- including
years before the reformation.
It's better to be compatible with another tools than try to be perfect :-)
