[patch] manual/examples/longopt.c: make the options struct a little more like it should be

[Ben Collins <bcollins at debian dot org>]

2000-12-23  Ben Collins <bcollins@debian.org>

	* manual/examples/longopt.c: Make the "struct option" a little
	  more like it should be (adding usage of required_argument,
	  noargument and such, and also setting the options string
	  right).
