No, this isn't a GNUism.  The definition of set -e *really is* that
complicated.  This is mandated by POSIX.  And the definition is fluid,
changing every few years as people bring up newly discovered special
cases where it doesn't do the right thing, or is ambiguous or unclear.
Then they debate for a few weeks (months, years) and publish a new
interpretation.

Here's an example from 2009-2012: <http://austingroupbugs.net/view.php?id=52>
