In an ubuntu installation with the latest vm and Pharo 6 image when executing `./pharo --help` I get an error code of 1.

./pharo --help

echo $? �� --> returns 1

On mac the error code is 0. Also when executing './pharo' or './pharo Pharo.image --help' or './pharo --version' the error code is 0 on both mac and linux.

So it seems there is some issues with --help. Actually, it gives a usage warning, but still I'd expect to not return an error code.

Cheers,

Andrei��
