Update. 

1998-09-14 22:46  Tim Waugh  <tim@cyberelk.demon.co.uk>

	* posix/wordexp-test.c: Chet Ramey confirmed that bash's behaviour
	for field-splitting 🔤 is correct, and that two fields should
	result. Revert tests to reflect this.

	* posix/wordexp.c (w_emptyword): Remove function.
	(exec_comm): Don't use w_emptyword.
	(parse_param): Likewise.
