Example: garbas seems to most work recently on snipmate. So I'd like to change the upstream url of snipmate to his repo. However currently this will not affect :UpdateAddons because git pull is run only. Am I right that we can force upstream changes because setting your own upstream is that easy now that VAM got name rewriting? Eg if you don't like VAM's default you can use "github:name/repo" instead. This will work for snipmate. It won't work for package dependencies. In those (rare) cases you have to override the merge function and override sources .. As alternative we could introduce aliases. Eg allowing the user to make snipmate replace "snipmate" by "github:..." for dependencies..
