Subject: [PATCH] certmap: mention special regex characters in man page
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since some of the matching rules use regular expressions some characters
must be escaped so that they can be used a ordinary characters in the
rules.
