[PATCH] D75791: [clang-format] Added new option IndentExternBlock

[Marcus Johnson via cfe-commits]

I’m wondering if theres a way to tell if an option has been set in the clang-format config file.

If IndentExternBlock is not set, we should default to the old behavior.

As for your suggestion of setting IndentExternBlock to BraceWrapping.AfterExternBlock or negating it, neither way works with the tests.
