Can we have gnulib-tool.py emit the same copyright header?

[Collin Funk]

When creating a Makefile for example, the diff between gnulib-tool and
gnulib-tool.py is:

diff --git a/lib/gnulib.mk.in b/lib/gnulib.mk.in
index a718c17c0e8..15d15970051 100644
--- a/lib/gnulib.mk.in

The gnulib-tool.py one only does a single year instead of the range.

This diff is copied from the attached patch:

diff --git a/pygnulib/GLInfo.py b/pygnulib/GLInfo.py
index 808f11b06f..1759368268 100644

-        copyright = re.compile('^[0-9]*-').sub('', copyright)
         result = 'Copyright (C) %s' % copyright
         return result

The GNU Maintainer guide seems to disagree with this comment (assuming
that gnulib-tool.py is not a separate package) [1]. Am I missing
something or can we make this change?
