Interesting.  I do not think the reason why

	test -z && echo true

says "true" is "-z" noticed an empty string---it is "test $string"
that says "true" when "$string" is not a recognised command and is
not an empty string, no?

You are absolutely right that the above must be quoted.

Thanks for carefully reading.
