Thanks.  But now I'm **really** confused.  I don't why the first
subshell below (i.e. your version) terminates upon error but the
second one (mine) doesn't:

% ( set -e; printf a; false; printf b ); echo $?
a1
% ( set -e; printf a; false; printf b ) || echo $?
ab% 

Actually, I don't understand why mine doesn't work, period, since
I can't find anything in the zsh docs saying that it shouldn't...
Any pointers to the place in the zsh docs where this is explained
would be much appreciated.  (I hope that *some day* I'll learn to
find my way around the zsh documentation, but I'm nowhere near that
point yet.)
