This was in the first POSIX.1 spec (in the 1980's) and in the Bourne shell
before that.

I'll let you into a secret: it wasn't a "good" solution back when it was
added to the Bourne shell; the only saving grace then was that shell
scripts were rarely longer than a page, so it didn't matter as much.

I've just run a test in Bash v1.14.7 and (not unexpectedly) "set -e" had
the same effect there.
