>Description:
When shell function is called as a part of complex command with || operator, effect of -e (i.e. exit after first untested command returns error status) within that function is disabled.

>How-To-Repeat:
1. Create script
==> test.sh <==
set -e

qq ( ) {
  false
  echo ok
}

qq || echo failed
<end script>

2a) FreeBSD 4.11
Command:
 sh -e test.sh
<no output>

Command:
 bash -e test.sh
Output:
 ok

2b) FreeBSD 6.2
Command:
 sh -e test.sh
Output:
 ok

Command:
 bash -e test.sh
Output:
 ok

In all cases, expected output is:
 failed
