Thank you for the report (and sorry for the very late reply).

The attached patch upgrades to the latest help2man (version 1.47.7, 
released on September 2018).

Jim (and others):
For small questions about changes between the (very old) version 1.28 in
sed's git and version 1.47.7 from ftp.gnu.org:

1.
The copyright years changed:
===
-# Copyright (C) 1997-2018 Free Software Foundation, Inc.
+# Copyright (C) 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2009,
+# 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 Free Software 
Foundation, Inc.
===
Should this be changed?


2.
The shebang line changed like so:
===
-#!/usr/bin/env perl
+#!/usr/bin/perl -w
===
Should this be reverted? do we prefer "/usr/bin/env perl" ?
Debian's policy prefers "/usr/bin/perl" [1]
which I guess is why the script use it.

3.
The perl modules changed like so:
===
+use Text::ParseWords qw(shellwords);
+use Locale::gettext qw(gettext);
+use Encode qw(decode encode);
+use I18N::Langinfo qw(langinfo CODESET);
===

On OpenBSD, Alpine-Linux, CentOS7 the module "Locale/gettext.pm" is missing.
This does not affect building from tarball, as the pre-built "sed.1"
is packaged in the tar file.
It is only needed when building from git.

Is this a show-stopper?
