There was a problem hiding this comment.
There aren't any other user controlled parameters to git. It would be good to harden this with --end-of-options but we would then need to set a minimum git version so figured I'd pass for now as the needed versions aren't as universally available yet.
This reminds me: What is the minimal supported Git version we have?

I'm not aware of us specifying it or what it would be.

See https://nesbitt.io/2026/07/21/end-of-options.html While Cargo does support using the git cli, we are not subject to this because - we require URLs to be used in the `Cargo.toml`, `.cargo/config.toml` parser for git sources - we always prefix branches, revs, and tags or don't use them Tests are added to demonstrate this. I wasn't exhaustive (`patch`, `tag`, more `rev` kinds) but figured this was approriate based on source code inspection. There aren't any other user controlled parameters to git.
