DescriptionThe AGit flow (pushing to `refs/for/...`) did not check the pusher's access to pull requests again when it created the pull request. A user or deploy key with read access to the code only, or with write access to the wiki over SSH, could open pull requests in a repository where they have no access to pull requests. Creating a pull request through AGit now requires read access to the pull requests of the repository and is refused for wiki pushes.
