Bash Version: 2.04
Patch Level: 7
Release Status: release

Description:
The following script behaves differently in bash and sh:

    % cat script
    #!/bin/sh --
    checkstat() {
        echo $?
    }
    false
    checkstat
    # End of file

Repeat-By:

    $ type bash
    bash is /usr/bin/bash
    $ bash script
    1
    $ type sh
    sh is /usr/bin/sh
    $ sh script
    0

The 0 is wrong IMHO, it should be 1.  (Even HP with their BD-/bin/sh
returns 1).
