I have a branch called topic1 that is based on 'master'. For a particular file in my topic branch, I want to revert some changes by using my diff tool. I do this by comparing the original revision of the file with HEAD like so: $ git difftool $(git merge-base topic1 master) HEAD -- Path/SourceFile.cpp When I make changes to the right side (HEAD) through my diff tool, and exit, the changes aren't picked up and applied to my working copy. Since I'm modifying HEAD, I think it should carry over the changes I make. Is this by design or a defect? I don't know how else to selectively revert changes to a file through my diff viewer. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
