	Calling
	
		FOO=bar f
	
	where f is a ksh style function, should not set FOO in the current env.
	If f is a bourne style function, FOO should be set. Furthermore,
	the function should receive a correct value of FOO. Additionally,
	setting FOO in the function itself should not change the value in
	global environment.
	
	Inspired by PR 2450.
