That's right, because the front end was the wrong place to do it. Modern VCS diff tools automatically stay local when they can. Subversion diff does the right thing, and it's not even an issue in the 3G systems (they keep local repositories). It's the kind of variation that should be handled in the VCS-specific back ends. Actually CVS is the only awkward case. So what ought to happen is for something like the old stay-local logic to be implemented in the CVS back end. This is one of my two remaining to-do items for the mode. But someone who is more of a CVS expert than I might get it done faster. -- Eric S. Raymond
