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 220.127.116.11). If anyone cares about the revision
number of any particular file, I can check for it.

Sure you're not thinking of this? (Note the lack of "in".)
