Hi all,

please review this patch that makes the CLI tools **not** show an error when required flags and inputs are missing _and_ the flag `--version` is specified. If a user runs `git <tool> --version` then they shouldn't have to add required flags or input, they just want to see the version.

- [x] Manual testing on Linux x64
