Add in-place reformat

[okainov]

Clang-format allows to do in-place reformatting with -i option. Would be useful to have the same in the script as well.

Example - using in git pre-commit hook to auto-format all the files. Probably it should still exit with non-zero exit code if at least one file was reformatted though.

I would recommend git clang-format for this kind of things, it already supports that.

I agree -i could be nice to have. git clang-format is good for formatting single files or commits, but I want to reformat the whole source tree of my project in one go. I've simply added -i in the correct place in the code, this did the job, but could be generally useful.

I believe this issue can be closed, as the -i flag has been added in:

Indeed, closing, thank you.
