statichttprepo: prevent loading dirstate over HTTP on node lookup (issue5717) This seems a bit hacky, but works well. There should be no reason that static-http repo had to load dirstate. Initially I tried to proxy os.stat() call through vfs so that statichttpvfs could hook it, but there wasn't a good error value which the statichttpvfs could return to get around the util.filestat issue.
