Well, Greg does have a pretty good point (which is a point I for one
prioritize in my decision process for "do I personally recommend the use
of set -e") in that another part of the issue is its doing different
things across point releases of a shell.

And that's not counting the times when the issue is people not
understanding when it *is* in effect.

Or people who know exactly when it is and isn't in effect, and have no
issue, but decline to use it because the precise nature of "when it is
and isn't in effect" decreases the usefulness of it sufficiently to make
them decide they're better off implementing error checking a different
way... and *that* is, I think, what Greg is pointing out.
