From 95356d6189f5e5d41011a7cb60176f147e1fff7d Mon Sep 17 00:00:00 2001
From: Kristaps Dzonsons <kristaps@bsd.lv>
Date: Mon, 17 May 2010 22:11:42 +0000
Subject: Enable the unified error/warning enumeration in mandoc.h that's
 stringified in main.c.

Allow `An' to handle an argument and child (with a warning).

Allow `Rv' and `Ex' to work without a prior `Nm' as groff does (with a
warning).

Allow inconsistent column syntax to only raise a warning.
