Thank you, I had working on forgejo / codeberg SourceURL docs on my TODO list! Two questions:

1. Is there no URL pattern that would let us avoid the "HTML anchor trick"? It might be time to just drop that entirely, having just the version / commit be the filename base is perfectly fine in most cases ..
2. Is the contained folder really just the project name, without commit or version information? That seems ... a strange "choice", or is it a bug on the forgejo side? Might be good to investigate before hard-coding it into our guidelines.

We should ask the Forgejo people to add it the URL pattern we want. I did that years ago with GitLab, and they did add it for us. They try to be GitHub-compatible, so this might fall under that anyway.

We should just update our guidelines to use %autosetup -C instead, so people can stop thinking about the top-level directory.
