This commit improves the `cmd_psuh` documentation example by: Correcting the function signature to include struct repository *repo. Makes the signature accurate and consistent with typical Git built-in commands. Removing the `UNUSED` macros from the `cmd_psuh` function arguments (argc, argv, prefix, repo). This is done because the example now uses these arguments. Showing how to access the repository's Git directory (repo->gitdir) within the cmd_psuh function. This provides a practical example of how to use the repo argument and repository-related information. Keeps your existing printf() calls in place. This lets the users see the arguments which is given to the function. This enhanced example provides a more complete illustration of Adding a Git built-in command and use the repository argument.
