FYI: this breaks the tool:

```bash
git clang-format --binary /usr/bin/clang-format --extensions $INPUT_EXTENSIONS --diff origin/$INPUT_TARGET_BRANCH origin/$INPUT_SOURCE_BRANCH
`/usr/bin/clang-format -list-ignored` returned 1
clang-format: Unknown command line argument '-list-ignored'.  Try: '/usr/bin/clang-format --help'
clang-format: Did you mean '--lines'?
```
