>Description:
The following shell script does not work as it should:

#!/bin/sh
set -e

is_net_dir_p()
{
        case $1 in
        /net/*)
                return 0
                ;;
        *)      return 1
                ;;
        esac
}


if is_net_dir_p freebsd; then
        echo okay
fi
echo done

---
A properly working /bin/sh would print 'done' and exit.  Currently
nothing is printed and the shell silently exits.

The man page for 'sh' says:

     -e errexit
             If not interactive, exit immediately if any untested command
             fails.  The exit status of a command is considered to be explic-
             itly tested if the command is used to control an if, elif, while,
             or until; or if the command is the left hand operand of an ``&&''
             or ``||'' operator.

>How-To-Repeat:
Run my script above.
