<pre>
    I am developing the WASM version of clang-format and testing the CLI that comes with it.  (https://github.com/wasm-fmt/clang-format)
I've encountered issues with the non-standard CLI options generated by git-clang-format, which complicates the parsing process.

Typically, clang-format's CLI options are structured as follows:

```
-i                             - Inplace edit <file>s, if specified.
--style=<string>               - Set coding style.
```

This is a standard CLI option, with a single hyphen representing a short option and a double hyphen representing a long option. However, CLI options generated by git-clang-format appear differently:

https://github.com/llvm/llvm-project/blob/73c72f2c6505d5bc8b47bb0420f6cba5b24270fe/clang/tools/clang-format/git-clang-format#L502

In typical cli parsing libraries, the `-style` option is synonymous with `-s -t -y -l -e`, which has been a source of confusion for me.
