Creating a patch queue doesn't clone the wiki repository.
Correct me if I'm wrong. When creating a patch queue the original code repo is cloned (and mq is initialized in it) so the user is able to pull changes from it. I assume the wiki isn't (it's probably created from scratch) because I'm getting "repository is unrelated" message when trying to pull updates from the original wiki repo and the initial changeset ids are different (in contrary to code repos).
It would be nice to be able to use the same workflow when working with the wiki repo (work on the documentation using patches).
