Agreed.  But one of the biggest traps for beginners in Bourne Shell
programming is exemplified by the fact that you can't write
	for i in *
	do
		cat $i
	done
safely unless you're sure that there are files in the current directory.
IMHO, what's wanted is
	set nullglobok
which inhibits both "no match" errors (which are almost never what I want
in shell scripts anyway) and the funny behaviour of nonmatching patterns.

If "bash" (instead of "sh" (i.e. BASH emulating the Bourne Shell)) is
started non-interactively, then I would probably choose "nullglobok" to be
set by default.  But this is more a matter of taste.

I've taught quite a few people Bourne Shell programming, and it'd have been
a lot easier for me if this feature had been available...
