This is not related to my problem since I am not running the script using ./foo.sh but directly using the proper shell. sh just behaves differently, that looks odd so I would like to know if it is a bug in sh or if there is no specification for this and the behaviour depends of the implementation of each shell, in which case I have to tweak the script I am porting to avoid this construct (passing $? as an argument for example).
