С другой стороны, субшелл отрбуает эффект -e с внешней стороны.
То есть можно написать
--- sisyphus_check/sisyphus_check- 2008-04-23 14:07:25 +0000
+++ sisyphus_check/sisyphus_check 2008-04-23 15:09:14 +0000
@@ -43,7 +43,8 @@ run_checks() {
check_var="$(printf '%s' "no_check_$check" |tr - _)"
if eval "[ -z \"\${$check_var-}\" ]"; then
- if ! (. "$sisyphus_check_d/$check" && run_check "$f"); then
+ (. "$sisyphus_check_d/$check" && run_check "$f")

Тогда всё что в субшелле будет выполняться в чистом -e режиме,
но статус субшелла не обрубает саму программу.
В общем, вопреки легенде, unix way изначально было не очень хоршо
продуман, и нужно им пользоваться острожно. Не злоупотреблять. :)
