add -f/--force to pull, incoming, outgoing, to work on unrelated repo. before this, push would not push from e.g. "hg" repo to "kernel" repo but other commands worked. this was bad idea, could merge unrelated projects by accident. i did this tonight. now, all commands still work with unrelated repo but need --force/-f. abort is default. this is safer.
