From d496e19d1130926a2bec10b227d83569f576cddf Mon Sep 17 00:00:00 2001
From: tb <tb@openbsd.org>
Date: Wed, 31 Aug 2016 04:48:43 +0000
Subject: [PATCH] Fix a bogus comment: "factors of" -> "coprime to".  Replace
 the nonsensical "if and only iff" with "if and only if" and zap some trailing
 whitespace.
