I have stumbled on a fix.  "format long e" followed by "format" does 
what I want.  Successive calls to "format ..." seem to be dependent on the
old state.  

(May I guess?  Does 2.0.16 use good old ugly but predictable <stdio.h> and 
2.1.30 beautiful trendily-orthodox but counter-intuitive <iostream>?)
