Yes, the above was a valuable clue!  It looks like the “Eurogreenies” are 
indeed at fault!

I just went, line by line, through all of the pmset -g settings, and I think I 
found the problem.

Somehow autopoweroff was set to 1.  autopoweroffdelay was set to 14400, which 
is 4 hours.

The man page says:  

autopoweroff is enabled by default on supported platforms as an implementation 
of Lot 6 to the European Energy-
     related Products Directive. After sleeping for <autopoweroffdelay> 
seconds, the system will write a hibernation
     image and go into a lower power chipset sleep. Wakeups from this state 
will take longer than wakeups from regu-
     lar sleep.

I’ve now set autopoweroff to 0, and I will leave the system untouched 
overnight. This should restore some sanity.
