Patch for /usr/bin/make docs


From: Max Okumoto <okumoto@home>
Date: Mon, 08 Nov 2004 01:31:28 -0800

When we merged in changes from FreeBSD/RELENG_4 on 2004/10/24
we missed the patch for make.1.  You can use the attached
patch or you can use cvs to extract it.

% cvs diff -u -rRELENG_4_9 -rRELENG_4 make.1
