Subject: [PATCH] gitweb: fix error in sanitize when highlight is enabled
Date: Sun, 30 Dec 2012 13:52:53 +0200 [thread overview]
Message-ID: <1356868373-12721-1-git-send-email-orgads@gmail.com> (raw)
$1 becomes undef by internal regex, since it has no capture groups.
Match against accpetable control characters using index() instead of a regex.
