"Edit this page" doesn't link to the right repository for API documentation
The swh-docs building process symlinks the documentation for individual modules into the swh-docs tree to generate a single sphinx project.
The "Edit this page" link will always point to the swh-docs repository, even if the source actually lives in another repository.
I'm not sure how easily we'll be able to hook into the generation of this link for individual pages, but I guess it's worth a try.
