An empty $* or $@ *should* be the same as having nothing there...and
indeed in a test I just did:

[Callisto] 21> sh
# echo $# 
# for i in $*; do echo $i; done 
# for i in; do echo $i; done

This sh binary is dated Jan 21, and the most recent date in the
$NetBSD$ lines output by "strings - /bin/sh | egrep NetBSD" is
1997/11/13 (histedit.c  If anyone cares about the revision
number of any particular file, I can check for it.
