This is in fact what happens when `allexport' is NOT set.

It'd have to be +x for local, -x for exported, to be consistent with
existing usage.

I confess to be curious why:

	setopt allexport
	typeset +x FOO=bar

results in FOO being exported, whereas

	setopt allexport
	FOO=bar
	typeset +x FOO

results in FOO being local.  Does ksh really ignore the `+x' in the
first example?  (I should get pdksh so I can stop asking this stuff,
but then again, most of the time I don't *want* pdksh.)
