Then what I want is something like:

Content-Type: text/plain; charset=US-ASCII

sed -n -e 's,^Update of .*/cvsroot/,,p' | awk -F/ 'BEGIN{ n = -1 } { 
	if(n == -1)
		n = split($0, x, "/"); 
	else { 
		if(n > NF) 
			n = NF; 
		for(i = 1; i <= n; i++) 
			if(x[i] != $i) { 
				n = i-1; 
				break 
			} 
		} 
	}
	END { for(i = 1; i <= n; i++) printf(x[i] "/"); print "" }'

Of the 247 mails I have since July 13, 5 had totally different paths,
194 had 3 or more components in common.
