	Sorry, my bad.  I should have said that "N" was any positive
	integer.   Sometimes I'll be searching for a phrase that i'm
	not certain of and will type grep -7 PATTERN file[s] where

	this tgrep is from the NL; by a Prof Piet van Oostrum and is
	dated 5/19/93.  i think ii wrote this fellow many years ago.
