wmaker set errorlevel to 0, even when failure to start

[Michele Bert]

Hello.
I don't know it is already known and/or wanted behavior, but even though
windowmaker does not start (for example because the $DISPLAY is wrongly
set), the error code returned is 0. That means you cannot test the
successful of the call with sometnig like:

if wmaker
then
    echo Success
else
    do-something-to-investigate-the-problem
fi

It isn't very important, bu I was just curious about the reason of such
behavior.
Thanks in advance,
