This behavior is one of the consequences of the Austin Group's interpretation.
Failures of user-specified subshells cause the shell to exit when set -e is
in effect. The key piece of the interpretation was to widen the scope of
commands that cause the shell to exit without an explicit exception from
simple commands to all commands.
