I agree with Andrey -- although this has the possibility of breaking
old scripts that expect no output from echoing an empty variable.
Since the DEC/OSF system update script only works with their ancient
/bin/sh (and not with the XPG4 sh) I wouldn't be surprised to find
such scripts out there... :-)
