cannot blame binary file {:?} at revision {revision}

Error message

cannot blame binary file {:?} at revision {revision}

What it means

Raised while producing a blame for a buffer: the file at the given repository path is binary at the requested revision, so `git blame` cannot produce line-level attribution. The operation is rejected rather than returning meaningless output.
