Fix walkhelper on windows.

The ''seen'' dictionary stores paths in canonical form,
so the walkhelp must also provide paths in that form,
otherwise the changed files are listed twice.

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
