Add node changes to the comment after saving

Hi,
Since long time I searched to do something similar to project issues for D7

I found your interesting modules and also nodechanges who stores the changes of a node into a field attached to comments.

I combined both module to display changes on the comment.

If you want test, install nodechanges and enable only "Node revision diff field".
Add a "comment diff" field in comment fields on your content type with unlimited in number of values.
Allow create a new revision in your content type
apply patch
and enjoy !
