clone: pass on the repository instance rather than the string given Previously, cloning a Mercurial repository that required authentication would prompt for authentication twice. This is because hgclonewrapper() first created a repository instance, but didn't pass it on. hg.close() would then create another instance, and since Mercurial doesn't cache authentication credentials across instances, this would cause a second credential prompt. This change could have unfortunate side effects in case of other extensions wanting to modify the source passed to clone. This seems like a somewhat unlikely scenario. I'll think about a possible way to avoid all this hackery...
