Subject: [PATCH 25/24] tighten up digit matches to ASCII for git output
Date: Wed,  5 Jun 2019 02:18:48 +0000	[thread overview]
Message-ID: <20190605021848.29258-1-e@80x24.org> (raw)
In-Reply-To: <20190604112748.23598-1-e@80x24.org>

While I don't expect git to suddenly start spewing non-ASCII
digits in places I'd expect ASCII, this would make things easier
for future hackers and reviewers.
