This is not true, strictly speaking. The `-e' option applies to only
simple commands. Bash does make `-e' apply to pipelines whose last
element is a simple command, but only for compatibility with historical
shell implementations. That accounts for the apparent anomaly.
Posix is not exactly clear on this topic, but I believe bash's
interpretation is conformant.
