Actually, you can change the shell.  (Nowadays, that's more like three to
five things.)  For example, I would REALLY appreciate in csh a variable

	set expandcheck=5

So that if some shell expansion expanded to more than 5 things, it would
prompt for confirmation:

	% rm * .o
	*: matches 400 files, are you sure?

Comments on this idea?  --Alan
