Fix formatting of example blocks

With the new stylesheet example blocks (delimited with ====) are
rendered as rather intrusive boxes with large padding in yellow
and grey.

This patch replaces the example blocks with simple code blocks
(delimited with ----) that better match the overall style of the
documentation.

 If the replication plugin is installed, the plugin will attempt to
 perform remote repository creation by a Bourne shell script:
 
-====

   mkdir -p '/base/project.git' && cd '/base/project.git' && git init --bare && git update-ref HEAD refs/heads/master

 For this to work successfully the remote system must be able to run
 arbitrary shell scripts, and must have `git` in the user's PATH
