Subject: [PATCH 2/2] gitweb: remove invalid http-equiv="content-type"
Date: Sun,  6 Mar 2022 22:37:23 -0500
Message-Id: <20220307033723.175553-3-jason@jasonyundt.email>
In-Reply-To: <20220307033723.175553-1-jason@jasonyundt.email>

Before this change, gitweb would generate pages which included:

	<meta http-equiv="content-type" content="application/xhtml+xml; charset=utf-8"/>

A meta element with http-equiv="content-type" is said to be in the
"Encoding declaration state". According to the HTML Standard,

	The Encoding declaration state may be used in HTML documents,
	but elements with an http-equiv attribute in that state must not
	be used in XML documents.

	Source: <https://html.spec.whatwg.org/multipage/semantics.html#attr-meta-http-equiv-content-type>

This change removes that meta element since gitweb always generates XML
documents.
