Subject: gitweb: escape link body in format_ref_marker
X-Git-Tag: v2.9.3~11^2

gitweb: escape link body in format_ref_marker

Fix a case where an html link can be generated from unescaped input
resulting in invalid strict xhtml or potentially injected code.

An overview of a repo with a tag "1.0.0&0.0.1" would previously result
in an unescaped ampersand in the link body.
