Add repository directory argument to diffargs offerings
Created originally on Bitbucket by Brandon Jones
I have a specific need to copy the diff files ($child and $parent) to another directory so that dependencies of those files are found. I can do this just fine for merging as I have $output available to me, which allows me to pull the repository path from it. I do not however have this available to me from diffargs.
I am calling a batch file that launches an executable to difference the files, and I need to find out what the path to the repository is so that I can correct dependency issues, as TortoiseHG copies these files to be diffed to a temp directory, breaking my dependencies.
