Change 140394 by gabor at gabor_server on 2008/04/22 08:42:51

	Add my initial version of the grep, sort and diff for my
	Summer of Code 2008 project. These version are in sync with
	the versions of OpenBSD and furthermore contain small
	additions:
		- Added support for long command line options to sort
		- Man page completion for all of the three utilities
		- Comments about missing / incomplete features
	
	Obtained from:	OpenBSD
