Hi, the latest invoke-diff-cmd branch:
http://svn.apache.org/viewvc?view=revision&revision=1538071 is ready to be merged into the trunk, iff everyone agrees that the current substitution syntax is just right and the documentation and the code itself is of acceptable standard. If at all possible, it would be convenient if the invoke-diff-cmd branch is not deleted quite yet, because I'm using a particular merge revision in that branch for testing the forthcoming invoke-merge-cmd feature.
