Fix default clone destination

The default clone wasn't working:

$ hg clone hg
abort: repository hg/.hg not found!

This was because we were creating the destination directory from the
default, then checking whether it existed to determine whether to
expand the path.

def demandload(scope, modules):
    class d:
        def __getattr__(self, name):
            mod = self.__dict__["mod"]
            scope = self.__dict__["scope"]
            scope[mod] = __import__(mod, scope, scope, [])
            return getattr(scope[mod], name)

    for m in modules.split():
        dl = d()
        dl.mod = m
        dl.scope = scope
        scope[m] = dl
