Where to find the Joomla! 1.5\2.5 to monitor changes in site files?

Question

Joomla

Need a Joomla! 1.5\2.5 to monitor changes in site files.
The Eyesite module only shows which files have been changed, it does not show the changes themselves.
For example
it was:

<?php
Hello world!
?>

became:

<?php
Hello world!
Bye moon!
?>

This needs to be tracked. What/where added.
Hosting from mchost, not vps.
