That is much clearer language than in the POSIX 1003.2 draft. In the posix language one could infer that the entire command line is the "result of expanding I whould also note that the Korn shell I tested on SunOS-5 is "Version 11/16/88i". However I don't think the XPG 4.2 wording makes any sense at all, nor do I agree that the behaviour of the current shell is "correct". Such field splitting is essentially useless since it requires silly work arounds that add unnecessary code, as revealed by the bugs it causes with GNU Autoconf generated scripts. It is possible that there's something I'm missing here and that the current behaviour actually fills some imporant niche, but I don't see it just now. -- Greg A.
