I think it should work simply because there might be a script with the line
	$ cp {$*} /tmp
which would fail if only 1 arg was passed via the command line. Besides,
it works ok in csh.
Also, I've got Korn's book on ksh but can't find any reference to {} in
pathname expansion; nor in the ksh man page. Maybe it's undocumented
because it's a little buggy and not officially supported yet.
