From: Orgad Shaneh Date: Sun, 30 Dec 2012 11:52:53 GMT Subject: [PATCH] gitweb: fix error in sanitize when highlight is enabled Message-ID: <1356868373-12721-1-git-send-email-orgads@gmail.com> $1 becomes undef by internal regex, since it has no capture groups. Match against accpetable control characters using index() instead of a regex.
