>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.

Run my script above.
