FYI: That didn't work.

FYI:  That didn't work either.

I suspect these things didn't work because of my own .emacs, which
is old and woolly.

Good idea.  That worked!

Thanks for these suggestions.

In the end, an even better approach, at least for our purposes, may be
global-auto-revert-mode.  I am chagrined to discover that this mode
has been around for a while, and I just didn't know it.  Until I read
your suggestions, I had never understood that, in the jargon of Emacs,
"revert-buffer", means "update the buffer".  

I'm curious about this usage of the word "revert".  "Revert" normally
connotes some sort of retrograde motion.  As far as I know, it never
connotes forward motion at all, much less forward motion undertaken to
catch up with someone else's forward motion.  But, until I'm
corrected, that's how I'll understand "revert" in the context of Emacs.
