Subject: [PATCH 36/37] hval: split out escape sequences to a separate table
Date: Mon, 21 Jan 2019 20:52:52 +0000 [thread overview]
Message-ID: <20190121205253.10455-37-e@80x24.org> (raw)
In-Reply-To: <20190121205253.10455-1-e@80x24.org>
We'll want to handle those escape sequences independently,
"highlight" already does HTML escaping.
