Code Owner for clang-format

Hi,

I would like to nominate Daniel Jasper as code owner for clang-format.
According to phabricator, he is either authoring or reviewing most of
the clang-format changes.

-Tom

Seems fine to me: Richard, any objection?

-Chris

This sounds like a very good idea to me.

Great, Daniel, assuming you accept the position, congrats! Please update the code owners file.

-Chris

I do :slight_smile:
