Much more rigorous testing -- we now try many times, varying in time
of day, day of week, and season. Fix the weekday predictions -- these seemed to be all bogus. The new predictions seem to correspond with strftime() on Solaris and IRIX, so I believe they are correct. Get rid of the test for non-standard format %C returning "the same as date(1)". This is hard to do reliably without opening a pipe to date, and moreover, on IRIX 6.2, %C yields the Century. So we use that instead. (We don't complain about this in non-verbose mode anyway.)
