The answer turned out to be a bogus saved tool option of some kind.  Here's what worked:

(1) Edit->Preferences->Tool Options->Reset Saved Tool Options To Default Values
(2) Restart gimp.

Actually Blighty's post #3 is the real answer. Your action has just reset the Selection tool to Replace mode which is its default.

if you want Gimp to always start with known options: see here.

No.  The "real" answer did not work.  Even with the "real" answer I could not escape subtract mode, period, nor could I find a way to escape it.  It was horrible to discard all tool options and restart.

What I'm hoping is that someone might explain how I *should* have escaped from an endless succession of dialog boxes complaining that you can't subtract from nothing.  The method I found is still the only method I know, but I doubt it's the only way.

Make a screenshot of your UI, then, showing the Tools options dialog.
