From 98c9347c157d5cfbd1ff157dd1087e2143adc3f0 Mon Sep 17 00:00:00 2001
From: Michael Kerrisk <mtk.manpages@gmail.com>
Date: Thu, 31 Dec 2020 09:41:12 +0100
Subject: [PATCH] Various pages: Formatting fix

Use .PP (which gives a bit of vertical white space) rather than
.br to separate functions in Feature Test Macro requirement lists.
