Sigh.  Someday maybe I'll decide not to answer email in the middle of the 
night when I've been taking decongestants.

As has been pointed out by Raúl, I've been telling you to avoid zsh while 
giving an example that uses a zsh builtin.

Try this one:

	toall sleep echo "this has          ten spaces"

With $@, you should get

	this has ten spaces 19980

Whereas "$@" should give

	this has          ten spaces 19980

And I should have remembered, as Dan Nelson mentioned, that $pipestatus is
only available in bash and zsh and therefore not portable.
