Research direction
Investigate how `rtk git diff` passes arguments to the underlying git command. The error suggests that the tool is misinterpreting file paths as revision arguments. Look into the git diff argument parsing logic in the repository, likely in a module handling git commands. Review the code that constructs the git command and compare with how git itself handles multiple file arguments separated by ` `. The fix may involve correctly separating options from paths.
