title: Regenerate conflicts of completed TFS merges
body: <p>I have recently discovered that I was using my third party diff/merge tool incorrectly when resolving conflicts encountered merging from the trunk to my team branch. As far as I know, only files that were merged in the merge tool were affected. I know how to use tf merge /force to re-do a merge, but I don't want to re-merge every file if I can avoid it, just the ones that I had to merge manually. Is there any way to get a list of such files now, long after the merge changesets have been checked in?</p>
