Michael, thanks for your kind and helpful reply.

The first time after I put that line in my config file, it worked
almost, but not completely.  It hung at:

Opening connection for lunar using scp...done

After about a half minute I did C-g, then did C-x C-s a second time and
it worked.  That's a vast improvement over most previous behavior. 

The second time (again, after coming out of sleep mode) going into an
already-opened buffer, making a change and then trying to save to disk
(on the remote machine), it worked flawlessly.

The third time (doing exactly the same as I did the first and second
times), it again worked flawlessly.

So I'm optimistic.  Thanks again.
