new mkgroup patch

[Joshua Daniel Franklin <joshuadfranklin at yahoo dot com>]

Here is a new patch that retains the multiple fprintf's instead of 
using a multiline one in the usage function. Also adds version option, etc.:

2002-03-16  Joshua Daniel Franklin <joshuadfranklin@yahoo.com>

	* mkgroup.c (usage): Simplify usage output.  Generalize to allow use
	for help. Correct '?' typo to 'h'.
	(longopts): Add version option.
	(opts): Add 'v' version option.
	(print_version): New function.
	(main): Accommodate new version option.  Accommodate usage parameter
	changes.  Use usage to output help message.
