What did you do?

Create a go.mod file with a replace directive with an unclean path on the right side. For example, the path might have a trailing slash, or a .. component in the middle.

Run any command that updates go.mod.

What did you expect to see?

The replace directive should be updated with a clean path.

go list -m -json should report the clean path.

If -mod=readonly is used, go list -m -json should still report the clean path, but go.mod should not be updated.

What did you see instead?

No change.

This partially caused #36193.
